Introduction
This manual is about POPmail for IBM and compatible microcomputers that
run the MS-DOS operating system.  POPmail is an electronic mail (E-mail)
system, written by the Microcomputer & Workstation Networks Center at the
University of Minnesota. With the POPmail program, you can send and
receive E-mail messages locally or to and from large systems on campus and
around the world.  In addition to POPmail for the IBM, we also support an
Apple Macintosh version, although all references to POPmail in this manual
will pertain only to the IBM version unless specified otherwise.

POPmail uses the standard IBM character set to emulate a graphical user
interface (GUI).  For this reason, POPmail runs on a wide range of IBM PCs
and compatibles, including the earliest PCs which contained a monochrome
display adapter (with no graphics support).  In other words, POPmail does not
require that you install a special graphics display adapter in your computer.

With a GUI, you interact with the program by responding to graphical symbols
which appear on the computer screen, rather than by issuing single line
commands (as with the MS-DOS operating system).  Because of its graphical
user interface, POPmail is largely self-explanatory.  If you are familiar with
the GUI in Microsoft Windows or the Apple Macintosh operating system, you
will be able to run POPmail without much help from this manual.

We allow free distribution of POPmail to all interested parties as long
as our copyright notices are not altered or removed and you do not
charge others for distribution of our software.

Help!
If you run into difficulties installing or using POPmail, you should first
contact your local network administrator.  If you have questions, bug reports,
suggestions, or general comments about POPmail you can send E-mail to us

POPmail User's Guide

Background and Philosophy
To be widely effective, an E-mail system must embody these three qualities:
wide connectivity, ease of use, and reasonable cost.  We designed POPmail to
meet these goals.  Wide connectivity is crucial because most people don╒t want
to use three or four different E-mail packages to communicate with colleagues
who use different computers.  You can use POPmail to send and receive E-
mail to and from the academic computer centers on campus Academic
Computing Services (ACS), St. Paul Computer Center (SPCS), Health Sciences
Computer Services (HSCS) as well as departmental minicomputers and
workstations.  Moreover, you can use POPmail to send and receive E-mail to
and from machines on the worldwide Internet (CICNET, NSFNET, and
MRNET) and on BITNET.  POPmail is easy to use and it is in the public
domain (it╒s free).

Because Unix machines have excellent connectivity to other systems, they
are a good choice for a mail server.  However, most non-technical users
do not want to learn to use Unix just to use E-mail.  For this reason,
we achieved POPmail╒s design goals on the IBM by writing the program in
Turbo Pascal so we could hide the ugly realities of the traditional Unix
mail system from the POPmail user.  By developing our own custom
application with an intuitive user interface to the Unix mail system, we
can give POPmail users the best of both worlds: wide connectivity and
ease-of-use.

POPmail╒s name is derived from Post Office Protocol, the protocol that
defines how a computer can retrieve mail from another computer which
acts as a shared post office or mail-server.  POPmail uses the POP2 or
POP3 protocols to communicate between POPmail and a Unix mail server;
this setup lets us present an easy-to-use interface to the E-mail user.

In addition to connectivity, there is another reason to use POP and a
Unix machine as a post office.  Since microcomputers aren╒t usually left
on all the time, any reliable E-mail system will require a post office
machine (or host mail server) to hold mail that arrives when someone's
microcomputer is turned off.  The Unix mail server is available 24 hours
a day to receive and store incoming mail and the user can call for it
when it is convenient.

Selecting a Host Mail Server
POPmail requires a host computer to act as a central shared mail server.
Several host options are available to you.  The easiest option is to
sign up for mail-server-only service with ACS (the University╒s Academic
Computing Services department).  For $20 per year, ACS will provide you
with unlimited access to the ACS mainframe mail-server.  (For further
information about this service, you can call ACS Accounts at
612-625-1511.)

If you have access to a Unix-based computer in your department or work
group, you may want to use that machine as your host mail server.
Examples of small Unix hosts include SUN workstations, NeXT computers,
or Apple Macintosh IIs running the A/UX operating system.  Computers of
this size should be adequate for servicing around 150 POPmail users.

Another low-cost option you can consider for a host mail server is to
use our MailStop program.  MailStop is a mail-server application,
written by the Microcomputer and Workstation Networks Center, that runs
on Macintosh computers.  This server software is designed to service
client workstations, either IBM-compatibles or Macintosh computers, that
run POPmail.  MailStop is in the public domain and is included as part
of our overall POPmail package.  This means that MailStop, along with
POPmail, is available from us via anonymous FTP on the internet.  (See
the "Configuring POPmail" section below for details.)

In any case, to use POPmail, you designate one machine to use as a post
office (also known as a POP server).  Incoming mail is held in your
mailbox on the post office server until you use POPmail on your
microcomputer to call for the mail.  This process is similar to having
your paper mail held for you in a P.O.  box at the U.S.  Post Office.
Like the paper mail user, those who use POPmail don╒t need to know how
the post office business works; they just need to know how to collect
their mail.

Figure 1 is a diagram of a worksite that uses the ACS mainframe computer
as the mail server; the server is connected to the campus-wide backbone
network.  The worksite is running POPmail on both IBM and Macintosh
microcomputers.  The IBM computers on the top of the diagram are
connected to the campus backbone network by Ethernet cable and a LANmark
Ethernet telephone Type LDI-410.  (Making a connection to the Ethernet
backbone may entail running wires for the network and setting up a
LANmark phone connection.  If you do not have the wiring and phone in
place, call Telecommunications Services at 612-625-6333.)

Figure 1:  Sample POPmail Setup


The POPmail User Interface

The POPmail screen consists of two full-sized windows.  The Viewer Window
is for viewing messages which have been sent to you.  The Composer Window
is used to compose new messages to send to others.

In addition to POPmail's two full-sized windows, smaller windows, (dialog
boxes) pop up from time to time in response to commands you issue.

POPmail's Menu Bar
The very top line of the computer screen contains POPmail's menu bar with
five menu labels.  The menu bar looks like this:

    ║   Options   Edit   Group   Memo   Window

The menu bar is the primary mechanism you use to communicate with the
POPmail program.  The menus have "pull-down" labels; that is, when you
select Edit in the menu bar, a list of specific editing commands are
dropped down from the Edit menu label and displayed in a list.  If one
of the commands in a pull-down menu is followed by three periods (...),
choosing that command will result in the display of a modal dialog box
(explained later in this section).  If a command in a pull-down menu is
not followed by three periods, this means that once you choose it, the
indicated action will occur immediately.

You can use either a mouse or keyboard to select commands.  To use a
mouse, click on the desired menu title to display the pull-down menu.
(Use only the left mouse button if your mouse has more than one button).
Then click the desired command.  Alternatively, instead of clicking you
can push the mouse button down over a menu title and then continue to
hold the mouse button down while you drag straight down from the menu
title to the desired menu command, and then release the mouse button.
If you decide not to choose a command, just drag out of the boundaries
of the pull-down menu and no action will be performed.

To choose menu commands using the keyboard, first pull down the menu.
You do this by pressing the F10 key to make the menu bar active.  (When
the menu bar is active, one menu title is highlighted.) If the menu
title you want is not the one currently highlighted, use the arrow keys
to move to the right or left along the menu bar, until the menu title
you want to select appears highlighted.  (Alternatively, you can just
type the first letter of the menu title.) Then press the <ENTER> key.
This will cause the menu to pull-down (drop- down).  There is a hot-key
alternative method to pull-down a menu.  Hold the Alt key down while
typing the letter corresponding to the first letter of the menu title
you want (e.g., type Alt-G to pull-down the Group menu).  ╩The hot key
to pull-down the ║ menu (called the system menu) is Alt-Spacebar.

Once the menu you want is pulled down, use the up-down arrow keys to
highlight the command you want.  Then press <ENTER> to choose (perform)
the highlighted command.  (As a shortcut: press the key corresponding to
the highlighted letter of the desired command in order to choose that
command.)

Once you choose (perform) a menu command, POPmail will do one of two
things: carry out the command directly or display a modal dialog box.

POPmail's Status Bar

POPmail's status bar is located across the bottom line of the screen.
The status bar looks like this:

Alt-X  Exit     F2  Fetch    F3  Prev Msg     F4  Next Msg     F7  View    F8  Compose

The status bar contains "hot spots." Hot spots are located wherever
words occur in the status bar.  For example, "F3 Prev Msg" constitutes
one hot spot.  Hot spots are separated from each other by more than one
space.  When you click on a hot spot with a mouse, the indicated
function will occur.  For example, when you click on the words "F4 Next
Msg", POPmail allows you to view the next message stored in your mail
database, and when you click on the words "F8 Compose", POPmail will
display the Composer window, allowing you to compose an outgoing mail
message.

To activate a hot spot without using a mouse, you type a hot-key.  For
example, if you press the F8 function key, POPmail will display the
Composer window; and, if you type Alt-X, you will exit the POPmail
program.

The individual items under the pull-down menus are organized as follows.
Highlighted letters (shown here as capital letters) are used to perform
the various short-cuts described in the previous section and elsewhere
in this manual.

Note that the key (capital) letter associated with each command is not
always the first letter of the command.  In addition, some menu commands
are considered to be so important that they can be activated with a hot
key alternative.  These hot keys are also shown below.

Dialog boxes
Once you execute a menu command, POPmail will do one of two things:
either carry out the command immediately or display a dialog box.  If a
menu command is followed by three periods, (e.g., Save As...), the
command opens a modal dialog box.  A modal dialog box is essentially a
question-and-answer session which requires you to select choices and
fill in the blanks before POPmail will proceed.  Note that while a modal
dialog box is displayed, the menus and status bar hot spots are
inactive.

In order to set options in a dialog box, you use five basic on-screen
gadgets.  These five gadgets or "controls" are: radio buttons, check
boxes, software buttons, list boxes, and input boxes.  Figure 2 shows a
dialog box illustrating the five controls:

Figure 2: Modal Dialog Box


Software Buttons
With a mouse, you choose a software button by clicking on the button desired.
The modal dialog box shown in Figure 2 has two software buttons: Ok and
Cancel.  If you choose Ok, the choices you select in the dialog box are
instituted.  If you choose Cancel, nothing happens and the dialog box goes
away without instituting any of your changes.

If you don't have a mouse, use the keyboard command equivalents to
choose and activate a button.  Press the <TAB> key consecutively to
advance forward through the dialog box until the button you want becomes
highlighted and then press the <ENTER> key to choose that software
button.  (Press Shift-<TAB> to move backwards in a dialog box.) When you
have finished making your choices in a dialog box, type Alt-O (to
activate the Ok button).  To cancel, type the ESC key.

Input Boxes
Input boxes let you enter text.  For example, in one of POPmail's dialog
boxes, POPmail requires that you enter your full name in an input box.
If you type in more text than will fit within the input box, the text
will scroll automatically.

Check Boxes

Some dialog boxes also have check boxes.  An X inside a square indicates
that that option is set ON.  An empty box indicates it's OFF.  You set a
check box to the ON- or OFF-state by clicking on the square or by
clicking on the text immediately to the right of the square.  (If you
don't have a mouse, press the <TAB> key one or more times until the
check box is highlighted and then press the Spacebar.  Alternatively,
you can turn a check box ON or OFF (toggling) by holding the Alt key
down while typing the highlighted letter (if one is provided).  Any
number of check boxes can be checked ON at any one time.

If several check boxes are grouped together, pressing the <TAB> moves to
the next group and once the group is selected, you can use the up-down
arrow keys to highlight the check box you want within the group, and
then press the Spacebar to turn the individual check box ON or OFF.  On
monochrome monitors, POPMail indicates the highlighted check box or
group of check boxes by placing a chevron symbol (╚) next to it.  When
you press <TAB>, the ╚ symbol moves to the next check box or group of
check boxes.

Radio Buttons
Radio buttons work just like check boxes, except that one and only one
radio button in a group is ON at any one time.  Since only one radio
button in a group can be ON at a time, any other button in the group
which was previously turned on is turned OFF automatically when you
select another.

List Box
A list box lets you scroll through a list of choices.  You activate a
list box by clicking in it or by pressing the <TAB> until it's
highlighted.  Once a list box is active, you can use the mouse to
manipulate the scroll bar (or if you don't have a mouse, press the
up-down arrow keys to move within the list).

(Note: Inside a dialog box, any item with a highlighted letter indicates
that that particular gadget can be accessed by holding the ALT key down
while typing that highlighted letter.)

Editing Text in POPmail
POPmail contains basic word-processing features.  Anywhere in POPmail,
the <DEL> key deletes text forward from the current cursor position, and
the <backspace> key deletes text to the left of the cursor position.
Except within a modal dialog box, you can use the mouse to drag over
(select) text to be cut or copied.  Without a mouse, you select text by
holding the Shift key down and using the arrow keys to expand the amount
of text selected, starting with the current cursor position.  Once the
text is selected (highlighted) you can cut the selected text, by
selecting Cut from the Edit menu.  Likewise, to copy selected text,
select Copy from the Edit menu.  Once selected text has been cut or
copied, it is stored temporarily in POPmail's clipboard.  To paste the
text contained in the clipboard, position the cursor in the desired
location and then select Paste from the Edit menu.

POPmail does not support underlined, bold, or italic text.

The current version of POPmail does not support word-wrapping; therefore,
when composing a message, always type the <ENTER> key at the end of each
line of text.  However, POPmail will scroll text automatically within the
message field.  Note: Users who are familiar with WordStar are advised that
the POPmail editor also supports the WordStar Control Key sequences for
cursor movement (Ctrl-E = Line Up; Ctrl-R = Page Up; Ctrl-F = Next Word;
Ctrl-Y = Delete Line, etc.).



POPmail Installation

System Requirements
In order to run POPmail, your microcomputer must be connected to a local
area network (LAN).  Usually, the LAN will be connected to the campus
backbone network, allowing you to send and receive mail outside your local
work group.

In order for your microcomputer to operate on the LAN, you must have a
network adapter card installed in your microcomputer.  In order to run
POPmail, your network adapter card must be one supported by the Clarkson
packet drivers, mentioned in the "Configuring POPmail" section below.
(For a list of network adapter cards currently supported by the Clarkson
Packet Drivers, please consult our accompanying documentation entitled
"Installing the Clarkson Packet Drivers".)

POPmail runs under DOS version 3.0 or greater and requires 640K of RAM.
POPmail was designed to run on a wide range of IBM PCs and compatibles,
including the earliest PCs which contained only a monochrome display
adapter (no graphics support).

A Microsoft-compatible mouse is helpful but optional.  You must load mouse
driver software into your system before running POPmail.  Note also that if
your mouse contains more than one mouse button, you will be using only the
left mouse button when running POPmail.

How to Obtain POPmail
POPmail software consists of two components: a Clarkson Packet driver
(matched to your microcomputer's network adapter card) and the POPmail
program software itself.  All the software components and their manuals are
included on the POPmail diskette, or they may be obtained on the internet
through anonymous FTP from

    boombox.micro.umn.edu

(IP address 128.101.95.95).  Look in the UNIX directory called

    /pub/POPmail

Loading POPmail and the Clarkson Packet Driver
Each Clarkson packet driver is a specialized piece of software designed
to talk to a specific type of network adapter card.  You install the
appropriate Clarkson packet driver according to the installation
instructions contained in the manual entitled "Installing the Clarkson
Packet Drivers."

In order to run POPmail, the appropriate Clarkson packet driver must be
loaded into RAM (random-access memory) each time you boot-up your
computer.  To do this, you first run the appropriate packet driver by
typing the packet driver name, followed by the necessary parameters, as
described in our accompanying documentation entitled "Installing the
Clarkson Packet Drivers".

After you have installed the appropriate packet driver, copy the
POPMAIL.EXE file into a directory.  If you want to be able to run POPmail
from any directory, modify the PATH statement in your AUTOEXEC.BAT file
to include the directory containing POPMAIL.EXE.  Then, you can run the
POPmail program by typing:  "POPMAIL" at the DOS prompt.

The following two command lines represent an example of the steps needed
to load the packet driver and start POPmail (of course, the specific
packet driver and parameters will depend on your configuration).  Type
each line following the command prompt and end each line by pressing the
<ENTER> key:

    3C523 0x60 0x3 0x300
    POPMAIL

At this point you are running POPmail.  As long as you do not turn the
power off to your computer, you can quit POPmail and do other things and
then start POPmail again without re-loading the Clarkson packet driver.
Also if you already have the packet driver loaded for other programs
like FTP, Telnet, or tn3270, you do not need to re-load the packet
driver before running POPmail.

Configuring POPmail
When you use POPmail for the first time, you need to set up POPmail
parameters.  POPmail needs these configuration parameters in order to
identify you and your computer on the network.  When you run POPmail for
the first time, POPmail will display the "Configure" dialog box shown in
Figure 3A, allowing you to enter the required parameters.  You must
enter all of the parameters, according to the instructions which follow.
(Consult your network administrator for the correct parameter
information.)  Space for entering multiple name servers and gateways is
provided, but only one of each is required.  You will not need to enter
parameter information during subsequent POPmail sessions, because
POPmail will permanently remember the parameters you have entered.  You
can modify your configuration settings at any time by selecting
Configure from the Options pull-down menu.



Figure 3A:  First Time Users


Initially, the User Name line will be empty and highlighted.  Since it
is already selected, you can simply type in your User Name.  To enter or
edit Full name, Password, or any of the other parameters in the
Configure dialog box, use the <TAB> key (or Up and Down arrow keys) to
advance to the appropriate parameter field.  Then enter the appropriate
parameter information.  (As a short-cut you can select any of the
parameter names by holding down the Alt key while typing the highlighted
character in that parameter name, e.g., type Alt-P to select the
Password parameter name.  Remember: In general, we use a capital letter
to designate a highlighted letter within a dialog box.)

A brief description of each of the parameters follows:

User Name
Initially, the User Name line will be empty and highlighted.  Since it
is already selected, you can simply type in your User Name.  This User
Name corresponds to the User Name (sometimes called the account name)
that has been assigned to you for use on the host mail server.
Generally, the host mail server will be a Unix machine, and by
convention, Unix machines use all lower-case letters, so be careful not
to capitalize letters in your user name when they shouldn't be.

Full Name
This is your full name in real life, e.g. John A. Doe.

Password
The Password is the key word that the host mail server uses to validate
your user name.  The person who sets up your account on the host mail
server will assign you this password.  Warning: Be sure to type in your
password exactly as it was assigned, (again, be careful of upper- and
lower-case considerations).  Note that when you enter your password in
the Configure dialog box, you will not see your actual password
displayed on the screen.  This is a security feature of the POPmail
program, since it prevents people from viewing your password as you
enter it.

Host Computer
This is the name or IP address of the computer you are using as a host
mail server for running POPmail.  Every computer on the TCP/IP
(world-wide) network has a unique numerical address called an IP
address.  The IP address looks something like 128.101.63.1.  In much the
same way as the post office uses home addresses to distinguish one
residence from another, the network uses IP addresses to distinguish one
computer from another when delivering electronic mail.  In addition to
having an IP address, each computer on the network often has a name,
e.g.  vx.acs.umn.edu.  Although both the IP address and name are unique
for each computer, they don't have equal status.  Specifying the host
mail server's IP address will always work to identify the host computer
successfully, while specifying its name identifier may not always work.
You can use either the host computer name or IP address.  The advantage
in using the name, although it is less reliable on the network, is that
it's easier to remember a name than it is to remember a series of
numbers.  If you use a name, the name will be converted to an IP address
by a computer on the network called a name server.

Microcomputer IP address
This is the IP address of your individual microcomputer or workstation.  See
your network administrator for a microcomputer IP address assignment.

Subdirectory for Mail
POPmail writes a copy of each message you receive to a file on your
personal computer, one file per message.  This parameter specifies the
drive and subdirectory for POPmail to use when saving your messages.  If
this subdirectory does not exist on your disk, POPmail will ask you if
you would like to create a new subdirectory when you exit the dialog
box.  (Note: POPmail will also ask you if you would like to create the
subdirectories called ENCL and ENCL\RSRC within your subdirectory.  See
the section called "About Enclosures" for more details.)

Gateways
A gateway is a device which gives your computer access to the outside
world, by transferring information from one type of network to another.
If you want to use POPmail to send messages beyond your local area
network (LAN), you must specify the IP address of one or more gateways
to which your LAN has access.  If more than one gateway is available to
you, it is to your advantage to enter more than one, increasing the
chance that you will find one that is up and running when POPmail needs
it.  A gateway moves your POPmail information off your LAN and routes it
on to the outside world.  Contact your network administrator for the IP
address of gateways accessible to your LAN.

Name Servers
As discussed earlier in the "Host Computer" section above, a name server
converts a host mail server name into an IP address.  You type in the IP
address of your name server in this parameter field (see your network
administrator for the value to enter).  If more than one name server is
available to you, it is to your advantage to enter more than one IP
address, increasing the chance that you will find a name server that is
up and running when POPmail needs it.

Time Zone
Figure 3B shows the Time Zone List Box which pops up when Figure 3A's
Time Zone software button is activated.  The Time Zone List Box allows
you to indicate your time zone, if you are not located within the
Central Standard Time zone of the United States, which is the default
setting.  To indicate your time zone, use the scroll arrows or the
up-down arrow keys, to select your time zone from the list.  Once your
time zone is highlighted, type the <ENTER> key or click on the Ok
button.

Figure 3B: Time Zone List Box


When you have finished entering the parameters, click on the Ok button
to have POPmail save your changes to the configuration.  If you decide
you don't want your parameter changes to be saved, click on the Cancel
button.

Advanced Configuration Parameters
Starting with Version 2.10, we have enhanced the Configure dialog box to
provide network administrators with more advanced and specialized
configuration parameters, in case they are needed to install POPmail on
network environments which have unique or unusual requirements (see
Figure 3C).  Network administrators can set these specialized parameters
by activating the Advanced software button found within the Configure
dialog box.  POPmail has appropriate default settings for these advanced
parameters, which in our experience are suitable for most networks.
However, if you encounter problems in installing or using POPmail on
your network, consult your network administrator to see whether it might
be helpful to alter the Advanced configuration parameters.

When the Advanced... software button is activated, the following advanced
configuration parameters are displayed:

Figure 3C:  Advanced Configuration Parameters

    a.    Net mask    255.255.255.0
    b.    Domain request timeout (sec)    20
    c.    Connect timeout (sec)    20
    d.    I/O timeout (sec)    20
    e.    Retransmit timeout in ticks    1
    f.    Max transmit unit in bytes: MTU    1024
    g.    Max segment we can receive: MAXSEG    1024
    h.    Most bytes we can receive without ACK    2048





Net mask
The net mask parameter has to do with how your local area network is
configured and connected to the backbone network at your work site.  See
your network administrator for the correct value to enter here.  Most
sites are configured to use a net mask of 255.255.255.0 (the default
value).

Domain request timeout  (sec)
This parameter sets the maximum number of seconds allowed for the name
server on the network to convert your computer's host mail server name
to an IP address.  The default value is set to 20 seconds.  If an error
dialog box is displayed stating "Domain name request failed" when trying
to send or fetch messages, try increasing this value.

Connect timeout  (sec)
When POPmail attempts to connect to the host mail server, this parameter
sets the maximum number of seconds POPmail will wait before the host
mail server will acknowledge your attempt to connect.  The default value
of 20 seconds is sufficient for most mail servers.  If an error dialog
box is displayed stating "Open failed" when trying to send or fetch
messages, try increasing this value.

I/O timeout  (sec)
This parameter sets the maximum time allowed for POPmail to send and
receive data from your computer to the host mail server.  With the
default value of 20 seconds, POPmail will wait 20 seconds for a response
from the host mail server.  If a response does not come through within
20 seconds, POPmail will present an error dialog box and abort the Send
or Fetch operation in progress.  Again, if your host mail server is slow
and frequently times out, you may need to increase this parameter value.

Retransmit timeout  in ticks
This parameter sets the length of time in sixtieths of a second POPmail
will wait before retransmitting a packet whose earlier transmission was
not acknowledged.

Max transmit unit in bytes:  MTU
This parameter specifies the maximum allowable packet size that POPmail
will transmit in bytes.

Max segment we can receive:  MAXSEG
This parameter specifies the maximum size packet in bytes that a host mail
server is allowed to transmit to POPmail.

Most bytes we can receive without ACK
This parameter sets the maximum send/receive TCP window size in bytes.



Using POPmail

Sending Mail to Other Users
Using POPmail to send an electronic mail message is easy.  Just follow these
steps:

1.    Make the Composer window the active window.
2.    Specify the recipient of the message.
3.    Specify recipients of carbon copies.
4.    Specify the subject of the message.
5.    Type the message itself.
6.    Send the message.

Make the Composer window the active window
Press the F8 function key.  This will make the Composer window active.  (The
active window always appears in front of all other windows.)

Specify Recipient
In order to send a letter to someone through the United States mail, you must
know their name and address.  Likewise, to send an electronic mail message
to someone, you need to know their electronic name and address.  This is
commonly called their E-mail address.

You place the recipient╒s E-mail address into the POPmail field labeled
To.  (Initially, the cursor is positioned in the To field).  In order to
move the cursor between fields, you press the <TAB> key or simply click
in the desired field with your mouse and then type the recipient's
e-mail address.  Figure 5 shows a sample message in the Composer window.

Figure 5:  POPmail screen with the Composer window visible
       ║   Options   Edit    Group   Memo   Window

           Alt-X  Exit     F2  Fetch     F3  Prev Msg     F4  Next Msg      F7  View     F8  Compose

In this example, the message is being sent simultaneously to two people.
One recipient is someone whose E-Mail address is:

    [e-mail]

(This address is read: kathy at boombox dot micro dot umn dot edu.  The
address denotes a person whose E-mail user-name is kathy.  Kathy gets
mail at a computer called boombox.micro.umn.edu on the Internet.)

To send the same message to more than one person, enter additional E-mail
addresses separated one from the other by one or more spaces (a comma is
optional).  The message in Figure 5 is also being sent to:

    [e-mail]

(a recipient named ellen who gets her mail at a computer called UMNMOR on
BITNET).  You can send the same message simultaneously to as many
recipients as you wish.

Specify Carbon Copies
With POPmail you can send a message directly to some people and as a
carbon copy to others.  After specifying the primary recipients of your
message in the To field, press the <TAB> key once to enter the CC field
where you can enter E- mail addresses of the people who are to receive
╥carbon copies╙ of the message.  To send carbon copies to more than one
person, enter additional E-mail addresses separated by one or more
spaces (a comma is optional).  Those who receive messages see E-mail
addresses of both the primary and the carbon copy recipients of the
message.  If you don╒t want to send carbon copies of your message, you
may leave the CC field blank.

Specify Subject
You must fill in the Subject field.  To move to this field, press the
<TAB> key.  Once your cursor is in the field, type a succinct one-line
description of your message.  Be courteous and wise; use this field to
describe the contents of your message briefly but clearly.  The subject
of our sample message is ╥Next Committee Meeting╙.

Type the Message
The big field just below the Subject field is the Message field.  This
is where you will enter the body of your message.  To move the cursor to
this field, press the <TAB> key again.  Once your cursor is in the
field, type your message.  Editing text here is easy.  You can use the
arrow keys to move around in the text and use the <backspace> and <DEL>
keys to delete text.  You can also use the WordStar control key
sequences for cursor movement.  POPmail uses a simple version of a word
processor and has some limitations.  For example, you cannot make text
bold, italic or underlined and you must type <ENTER> at the end of each
line of text.

Send Mail
When you are done typing your message click on the Send button
(alternatively, type Alt-S; or press the <TAB> key until the Send button
is highlighted and then press <ENTER>).  The message will be sent to the
recipients you specified in the To and CC fields.  When the message has
been sent to the mail-server, a confirmation dialog box is displayed.

Sending Mail to a Group
Sending POPmail to a group is as easy as sending a message to one
person.  With POPmail you can keep group lists.  A group is simply a
list of recipients (E-mail addresses) that have been given a one-word
alias (identifier).  For example, you could create a group called Marx
composed of these three E-mail addresses:

    [e-mail]
    [e-mail]
    [e-mail]

To create a group alias name, select the "Make Group..." menu item from
the Group pull down menu.  An edit box with scroll bars will appear to
allow you to enter the desired alias name and the recipients you want to
include in the group.  When you define a Group, you must type the group
name first.  In our example, shown in Figure 6 below, committee1 and
committee2 are group names.  The group names are followed by the user
names of the members of the group.  Within a group, each user name is
separated from the next by one or more spaces (commas are optional).
When you are finished entering the user names for one group, type the
<ENTER> key twice before entering information to define another group.
(Groups must be separated by a blank line.)

Figure 6:  Making Groups


When you have finished making groups, click on the Ok button to save
your changes.

Selecting a Predefined Group
To send mail to a group you have already defined, select the "Select
Group..." menu item from the "Group" pull down menu.  A list box with a
vertical scroll bar will appear, giving you a list of all your group
alias names, as shown in Figure 7.  Select the group name by typing the
up and down arrow keys until the desired group name becomes highlighted.
Then click on the Select button to select that group.  The "To" field of
the Composer window will be filled in automatically with the full E-mail
addresses of the members of the group; the group alias name itself does
not appear in the To box.

Figure 7:  Select  a Predefined Group



About Enclosures
POPmail allows you to enclose files, such as an Excel chart or
worksheet, or a memo created with Microsoft Word, with each mail
message.  Each recipient of your message receives an exact copy of the
enclosed files.  (Of course, to receive an enclosure from POPmail, the
recipient must be running POPmail/PC or POPMail/Macintosh.) Enclosed
files appear on the recipient's disk with their original contents.  Your
recipient can peruse and modify the file and, if desired, return it to
you as another POPmail enclosure.

When the POPmail program receives a message with an enclosed file, the
document is stored on your disk.  POPmail automatically stores the
enclosure in a subdirectory named ENCL of the directory you specify for
mail (see Configuring POPmail).  For example, if you specify the
C:\POPMAIL\MAIL directory for incoming mail, POPmail places your
enclosures in the directory C:\POPMAIL\MAIL\ENCL.

Since enclosures are regular files, you can treat them as you would any
other file; that is, if someone sends you an enclosure containing an
executable program, you can run the program on your machine as well.
In addition, an IBM enclosure containing graphics, italic or bold
characters, or spreadsheets, will retain all its original
characteristics.  In short, sending IBM files as enclosures is really no
different than transferring files from one machine to another using a
diskette.

Receiving Enclosures from a Macintosh
Macintosh files are somewhat more complicated than IBM files.  First,
Macintosh files can have longer and more complicated file names, so if
necessary, POPmail/PC will alter the original Macintosh file name in
order to comply with DOS file name requirements.  Second, Macintosh
files are divided into one or two forks (parts).  Part One, called the
"data fork," is completely equivalent to a data file on a DOS computer.
Part Two, if present, is called the "resource fork." The resource fork
contains special Macintosh-only information.  If an enclosure is coming
from a Macintosh, POPmail will store the data fork of the document in
the subdirectory called ENCL.  If the document also contains a resource
fork, the resource fork portion of the document will be stored in a
subdirectory of ENCL called RSRC.  For example, if someone sends you a
Macintosh HyperCard stack called "French," POPMail/PC will divide this
incoming Macintosh document into two parts.  Part One the data fork,
would have the name:

    C:\POPMAIL\MAIL\ENCL\FRENCH

Part 2 (the resource fork), would have the name:

    C:\POPMAIL\MAIL\ENCL\RSRC\FRENCH

Actually, the information contained in the resource fork is useless to the IBM
user; however, if someone sends you a HyperCard stack, you may want to pass
it on to another Macintosh user without losing any information.  That is why
POPmail saves the resource information on the PC even though PCs don't
have any way of using Macintosh-style resources.

Sending Enclosures to a Macintosh
It is possible to send enclosure files to a Macintosh, as well as
receive them.  In fact, many of the newer applications, such as
Microsoft Excel, have compatible data formats.  They achieve this by
using only the data fork on the Macintosh and storing the data in
compatible formats.

In general, if you are creating files on the IBM for later transmission
to a Macintosh via POPmail, you must be careful to assign the correct
file extension to your file name.  The Macintosh then will be able to
assign the proper system icon, etc.  to the IBM file when received.  For
example, if you are using Excel on an IBM and want to send the Excel
spreadsheet to a Macintosh user, your file name must have a .XLS file
extension.  The recipient will be able to receive and modify the
spreadsheet with no problem, and then send the modified spreadsheet back
to you.

Here are other important file extensions to employ when sending IBM
files to a Macintosh:

    EXT    Application    Document type
    ====     =========    ===========
    .XLS    MS Excel 2.2    spreadsheed
    .WKS    MS Excel 2.2    spreadsheed
    .WK1    MS Excel 2.2    spreadsheed
    .PAS    Turbo Pascal 1.1    program source
    .TXT    MacWrite II    ASCII text
    .BAT    MacWrite II    ASCII text
    .C    MS Word 4.0    ASCII text
    .CPP    MS Word 4.0    ASCII text
    .DOC    MS Word 4.0    internal
    .RTF    MS Word 4.0    RTF

Exchanging Documents:  Caveats
Those who exchange documents with others (via POPmail or even floppy disk)
using different versions of the same software soon learn that they cannot
always save, open, read, or retrieve documents in the usual manner.  New
versions of the software can usually open or read documents created with older
versions, but older versions do not recognize documents created with newer
versions.  However, newer versions of the software usually are backwardly
compatible in that they contain an option for reading and writing documents
in the old (obsolete) formats.

Exchanging computer documents is generally straightforward when you and
the recipient use exactly the same version of the same software; for
example, when you both use WordPerfect 5.1.  However, even in this
scenario, if the recipient does not have the font you used to create the
document, they probably will not be able to see the document as you
intend it to be reproduced - either on the screen or on a printer.

Whenever Microsoft Word users want to exchange documents but are unsure
of the recipient's software, they should save the document as an RTF
(rich text format) document.  Documents saved in this manner are
compatible with all versions of Word on the IBM and the Mac, as well as
with some other word processing programs.  Word 5.0 users will see the
RTF document's name show up in the Transfer/Load menu if the document's
name ends in .DOC.  If the document's name does not end in .DOC, Word
5.0 users must type in its name to load the document.  The newer Word
5.5 is more flexible; it has an option that lets you view a list of all
documents regardless of their names.

Some software comes with built-in file converters.  For example,
Microsoft Word for Windows 1.1 includes converters for several word
processing packages, such as Word for DOS, Word for Macintosh, Windows
Write, WordPerfect 5.1, and WordPerfect 4.2.  When you install Word for
Windows this conversion feature is automatically copied to your working
disk.  Not all software makes using its conversion features so easy to
use.  Some software requires that you follow special installation
instructions to use their converters.

Finally, keep in mind that when you E-mail large documents or multiple
enclosures, you can bog down a network.  To avoid congestion, consider
these strategies: send only one enclosure per mail message; break up
large documents into smaller documents; and mail your documents during
off-peak hours.

As you can see, enclosing E-mail documents is not always straightforward.
The less you know about the recipient's hardware and software setup, the
more likely you are to run into unforeseen problems.

Sending Enclosures
When sending a message, it is often desirable to enclose another file within
your message.  For example, you may want to send a message notifying others
of an upcoming committee meeting, and enclose a copy of a map indicating
directions to the meeting site.  If you push the "Enclose..." button in the
Composer window shown in Figure 8, POPmail will display the following
modal dialog box:

Figure 8: Enclosures Dialog Box


To add files to POPmail's enclosure list for this outgoing message,
click on the "Add..." button.  Then POPmail will display another modal
dialog box called "File to Enclose" (Figure 9) on top of the Enclosures
dialog box:

Figure 9: File to Enclose Dialog Box



The list displayed in Figure 9 is simply a list of all the files
contained on your disk.  The information at the bottom of the File to
Enclose dialog box (Fig.  9) is provided to give you further information
about the file you are proposing to select as an enclosure.  This
helpful information includes: drive, path, and file name information,
the file size in bytes, and the date and time the file was last
modified.  To select a document to be included in the list of documents
to be sent with the current outgoing message, click on the file name
desired and then click on the Ok button.  At this point, POPmail returns
you to the Enclosures dialog box, and your Enclosures dialog box will
display the name of the enclosure you just added, as shown in Figure 10:

Figure 10: Enclosures Dialog Box with Enclosure Entered


For each enclosure you wish to send, repeat this sequence, choosing one
file at a time, until you have chosen all the desired enclosures.  If
you find that you have selected an incorrect file, you can click on
(highlight) the incorrect file name and then delete it by clicking on
the Enclosures dialog box Remove button.  When your list of enclosures
is complete and correct, click on the OK button in the Enclosures dialog
box, and POPmail will return you to the Composer window.

Fetch Incoming Mail
Your incoming mail is held for you at the post-office server until you
fetch it.  When you fetch incoming mail, each message is moved from the
mail server to the POPmail subdirectory you have specified.  Incoming
messages remain in your database until you explicitly discard them.

To retrieve your new messages, click the Fetch button on the Viewer
window (Figure 11 below).  (No matter which window is currently active,
you can type Alt-F to make the Viewer window active and Fetch your
mail.) POPmail will present you with a dialog box to inform you whether
or not you have mail.  Then POPmail will display the first new message
in the Viewer window.


Figure 11: POPmail screen with the Viewer window visible
        ║   Options   Edit    Group   Memo   Window

            Alt-X  Exit     F2  Fetch     F3  Prev Msg     F4  Next Msg      F7  View     F8  Compose

If you are connected to a printer, you can print the message by
selecting Print from the File pull down menu.  If you want to delete the
message click on the Delete button in the Viewer window.  If you don╒t
delete the message, it will remain in the database.

Paging through the Database
Messages are stored in the database in the order they were received.
Each new message is stacked on top of its predecessor, just like file
cards on a stack.  To move backwards in the database (view the previous
message), press the F3 function key.  To move to the next message in the
stack, press the F4 function key.

Your incoming messages are saved to files on your disk in the
subdirectory you specify in the Configure dialog box (see Figure 3A).
The name of the file is the same as the message number.  For example, if
your message subdirectory is C:\POPMAIL\MAIL, message 324 will be stored
in the file C:\POPMAIL\MAIL\324.  When you Delete a message, the files
are not renumbered.

If you save a copy of your outgoing messages (specified in the Preferences
dialog box shown in Figure 12) from the Options pull-down menu, each
outgoing message will be numbered one larger than the highest message
number currently in your mail subdirectory.

Reply to Incoming Mail
One important difference between the Viewer window and the Composer
window shown earlier in Figure 5 is that the Viewer window includes a
REPLY button.  The Reply button allows you to respond to an incoming
message quickly, since POPmail automatically takes the Subject field and
From field information from the original message and fills it into the Subject
field and To field in the Composer window for your reply.  When you are
finished typing your reply, you click the Send button to send your message.

Setting Program Preferences
POPmail is designed so that you can customize the program to meet your
needs.  To customize POPmail, select "Preferences..." from the File
pull-down menu.  The Preferences dialog box shown in Figure 12 will
appear.  Use the mouse to click in the little box to the left of each
option in order to toggle the preference ON or OFF (when an X appears in
the box to the left of preference, it is turned ON).  (Using the
keyboard you can toggle a preference by pressing the Alt key together
with the letter that is highlighted for the preference in question; or,
press the <TAB> key repeatedly until the desired preference is selected
[highlighted] and then press the Spacebar to toggle that preference ON
or OFF.) The default values are pre-set by POPmail to the values shown
in Figure 12.  If you don't like these default values, you are free to
change them at any time.  POPmail permanently remembers your settings.

Figure 12: Preferences Dialog Box


The first preference option is "Include incoming message in Reply".
This feature is used in conjunction with the Reply button in the Viewer
window (see Fig.  11).  When there is a check in the square to the left
of this preference, POPmail will collect the text in the incoming
message and include it for reference as a preface to the reply you will
formulate to the message while using the Reply feature on the Viewer
window.  The text collected from the incoming message will appear before
your reply, with a leader line stating, " On [such and such a date] [so
and so] writes: ".  In addition, to further differentiate the incoming
message from your reply which will follow in the message field, POPmail
places a greater than (>) symbol before each line of the incoming
message.  You then type your reply following this reference text.  This
feature is useful because it allows each recipient of your reply to
consider your reply in the context of the original incoming message.

The second preference option is "Display POPmail's copyright screen".
When there is a check in the square to the left of this preference,
POPmail will display the POPmail copyright dialog box (POPmail's initial
screen) whenever you start up POPmail.

The third preference option is "Add signature to outgoing mail." When
there is a check in the square to the left of this preference, POPmail
will automatically end each of your outgoing messages with a signature
block of your choice, as shown in the John Doe example in Figure 12.

The fourth preference option is "Save copy of outgoing mail." When there
is a check in the square to the left of this preference, POPmail will
automatically place a copy of each outgoing message into your POPmail
database.  This convenient feature saves you a record of every message
you send.

Other Features

Moving a Window
You can move the Viewer and Composer windows, as well as dialog boxes,
by using a mouse or the keyboard.  Using a mouse, place the mouse cursor
on the top bar of the window frame, press the left mouse button, and
continue to hold the mouse button down while dragging the window to a
new location, then release the mouse button.  Using the keyboard, press
Ctrl-F5 (or select "Resize/Move" from the Window pull-down menu and use
the four arrow keys to move the window.  Press <ENTER> when done.)

Resizing a Window
The Clipboard window (you can view the clipboard by selecting "Show
Clipboard" from the Edit menu) and the Trace Window (see the "Trace
Facility" below) can be resized as well as moved.  To resize a window
using the mouse, grab the lower right corner of the frame and press the
left mouse button, dragging the mouse until the desired size is
achieved; or, using the keyboard, select "Resize/Move" from the Window
menu and use the arrow keys while holding the Shift key down.  Press
<ENTER> when done.  Note: The Composer window, the Viewer window, and
dialog boxes cannot be resized.

Trace Facility
POPmail has a built-in trace facility to assist network administrators
in trouble-shooting when POPmail fails to Fetch or Send properly.  When
tracing is turned ON, POPmail will write a detailed log of the
transactions between the PC and the host mail server when messages are
fetched or sent.  Then your network administrator can use this log to
help locate the source of the problem.  You press Alt-F10 to display the
Trace Options dialog box, as shown in Figure 13.

Figure 13:  Trace Options Dialog Box


By default tracing is turned off.  You turn tracing on by selecting a
trace destination, either the trace window or a file.

You can direct the trace output to a Trace window by choosing the "..╩to
╩trace window" radio button and then clicking on the Ok button.  Then a
movable and resizable Trace window is made visible and active.  You can
scroll back through this window to see earlier messages.  (The Trace
window has an 8k buffer).  All new messages are always added to the
bottom of the window.  If the Trace window gets covered by the Viewer or
Composer windows, you can bring it to the front by successively pressing
F6 (Next Window) until the Trace window appears on top of all other
windows.  You can close the Trace window by clicking in the close box in
the upper left-hand corner of the window or by pressing the <ESC> key.
Even if the Trace window is closed, transactions will still be recorded
to the trace window, you just won't be aware of them.  Remember, if you
have closed the Trace window, you can make it visible again by pressing
Alt-F10.

You can direct Trace output to a file by selecting the "..to╩file" radio
button and typing the name of the file in the input box just to the
right of this radio button and then clicking on the Ok button.  By
default, POPmail uses the file name "POPTRACE.TXT".  If you enter PRN
for the filename, the trace output will go to your printer.  If your
network administrator is unsuccessful in trouble- shooting the problem,
we can be more helpful if he or she sends us trace output.

The values you enter into the Trace dialog box are transient.  They are
forgotten once you quit the POPmail program.  The Trace dialog box
initial (default) settings are shown in Figure╩13.


Summary and Cautions
POPmail is designed to give networked microcomputer users an easy to use
E-mail system with wide connectivity.  While other Post Office Protocol
software for the PC already exists, POPmail/PC╒s user interface mirrors the
Macintosh POPmail user interface.  This consistency helps simplify training
for departments that have mixed Macintosh and PC computing environments.

Since there are many details to be considered in establishing a connection to
the campus backbone network, we strongly advise that you consult the staff at
the Microcomputer HelpLine before you plan your network or purchase any
hardware.

If you want to discuss POPmail (or other E-mail systems), call or visit the
Microcomputer HelpLine.  If you visit the HelpLine, our consultants can
demonstrate POPmail for you.  If your department decides to run POPmail, we
would be happy to help you set things up.


Acknowledgments
We wish to extend our thanks to Borland International of  Scotts Valley,
California, for continued excellence in the enhancement of their Turbo Pascal
product. We developed POPmail Version 2.0 using Borland's TurboVision, an
object-oriented library of special-purpose routines provided with Borland's
newest release of Turbo Pascal, Version 6.0.

For the use of the Clarkson Packet Drivers, the foundation on which our
network products are based, we gratefully acknowledge Clarkson College of
Potsdam, New York.

Using POPmail with Novell
Version 9.x of the Clarkson packet drivers will work with Novell NetWare.

First, you must configure Novell NetWare by using a special IPX.  It requires
that you SHGEN a new one using the driver from BYU to create the interface
between the packet driver and NET3/4/5.  The BYU_IPX is a generic IPX that
works with any of the boards that use the packet driver, so if you have a
mixture of 3COM, Novell Ethernet, and other boards you just need the
appropriate packet drivers and the BYU version of the IPX.

Second, to configure the packet driver to work with Novell NetWare, simply
add the -n switch to the command line immediately after the command to
invoke the driver, before any other parameters.  For example, to invoke the
packet driver for the 3COM 503 board, allowing for use with TCP/IP and Novell
NetWare, you would use the following command line:
    3c503.com -n 0x60 3 0x300


Using POPmail with Microsoft Windows 3.0
Version 9.x of the Clarkson packet drivers will work with Microsoft Windows
3.0.  To configure the packet driver to work with Windows 3.0 or greater, add
the -w switch to the command line immediately after the command to invoke
the driver, before any other parameters.  This allows you to use Windows to
invoke POPmail, Telnet, ftp, or tn3270 directly.  For example, to invoke the
packet driver for the 3COM 503 board, allowing for use with TCP/IP and to
work with Windows 3.0, you would use the following command:
    3c503.COM -w 0x60 3 0x300

If you want to use Windows and Novell NetWare together, your command lines
would look like this:
    BYU_IPX.COM
    3c503.COM -n -w 0x60 3 0x300

In addition, you will need to set up a separate Windows .PIF file for
each of the applications (POPmail, Telnet, ftp, and tn3270) with the
following options so that Windows can run these packet-driver-dependent
applications correctly:

    Full screen    ON
    Background execution    ON
    Close Window on Exit    ON

    Under "Advanced...":
        Background priority    100
        Detect Idle Time    OFF
        Lock Application Memory    ON
        Video Memory    TEXT
        Monitor Ports    OFF  (i.e., all boxes off)
        Retain Video Memory    ON

The .PIF file should point to the .EXE files for each of these programs.


POPmail Q & A
This section presents frequently-asked questions about POPmail/PC.

Q.    We have more than one Packet Driver loaded.  POPmail can't seem to
find the correct packet driver. What's going on?
A.    Popmail uses the first packet driver it finds.  Make sure the packet
driver POPmail needs has the lowest interrupt number. You can
ensure success by assigning it the lowest possible interrupt number:
0x60.

Q.    What language is POPmail written in?
A.    Turbo C version 1.5, Turbo Assembler 1.0, and Turbo Pascal 6.0

Q.    We are running a POP3 server on port 999.  Can we use POPmail with
this POP port?
A.    Yes.  To have POPmail use a port other than the default 109 port,
simply put the port number after the "Host computer:" field in the
configure dialog box.  For example:
        boombox.micro.umn.edu   999

Q.    I have a friend who gave me his access numbers on various computer
services including CompuServe, Prodigy, PC link, and Genie.  Can I
use POPmail to send him mail?
A.    For Prodigy, PC Link, and Genie we are not aware of any procedure
that would work.  Contact those services directly and ask them how to
send/receive mail to the TCP/IP internet. (When you are using
POPmail what you are really doing is sending TCP/IP internet e-mail).

    For CompuServe, you are in luck.
    Ñ From internet to Compuserve:
    Compuserve addresses are of the form  nnnnn,nnnn  where n is 0 to 9.
For example, 72555,3235.  Change the comma to a period and append
@compuserve.com and you've got it.  For example, to send to 72555,3235
you would address your mail to
        [e-mail]
    Ñ From Compuserve to internet:
    Preface the internet address with >INTERNET: and you're done.  For
example, to send mail to a user name fred with an account on an
internet mail server named boombox.micro.umn.edu from
Compuserve you would address mail to
        >INTERNET:[e-mail]
