- How to Send Fake Mail Using SMTP Servers
-
- By Hunter

- ---------------------------------------------------------------------------
- Overview
- SMTP (Simple Mail Transfer Protocol) is the protocol by which Internet mail
- is sent. SMTP servers use this protocol to communicate with other servers
- or mail clients. However, by telneting directly to a mail server and
- manually speaking SMTP, one can easily send mail from any address specified
- - meaning that mail can be sent from fake addresses while the sender's real
- address is untraceable.
-
- What is Needed?
- All that you need is a generic telnet client. Local echo should be turned
- on so you can see what you type. Also, it is important to note that SMTP
- servers do not handle backspaces, so you must type everything correctly.
-
- How do I Start?
- Telnet to port 25 of your target SMTP server (more on SMTP servers
- selection below). The server should respond with a generic welcome message.
- You will type HELO domain.name. Use any domain name you wish as most
- servers do not check the name against the IP you are telneting from. Type
- MAIL FROM: <from@wherever.com>. This is where the message will appear to be
- from. Next, type RCPT TO: <to@wherever.com>. This specifies who will
- receive the message. Type DATA and type the body of your message. To send
- the message, enter a line with only a period. Type QUIT to disconnect.
-
- Sample Session
-
- 220 hq.af.mil Sendmail 4.1/Mork-1.0 ready at Thu, 14 Mar 96 00:26:46 EST
- HELO prometheus.com
- 250 hq.af.mil Hello prometheus.com (prometheus.com), pleased to meet you
- MAIL FROM:<satan@hell.net>
- 250 <satan@hell.net>... Sender ok
- RCPT TO:<OJ@simpson.com>
- 250 <OJ@simpson.com>... Recipient ok
- DATA
- 354 Enter mail, end with "." on a line by itself
- This is the body of my message.
- .
- 250 Mail accepted
- QUIT
- 221 hq.af.mil delivering mail
-
- What about message subjects?
- The subject, date, to, etc. are part of the DATA area. After the DATA
- command, start with date and continue is the fashion illustrated by the
- example code below. Make sure there are no mistakes, because the first
- mistake will cause the data to appear in the body of the message, not
- header. It is interesting, because these fields take precedence over the
- MAIL FROM: and RCPT TO: when displaying. A message can be routed to a
- person even though the message itself appears to be addressed to someone
- else. The key is to type VERY carefully.
-
- Example:
- DATA
- Date: 23 Oct 81 11:22:33
- From: SMTP@HOSTY.ARPA
- To: JOE@HOSTW.ARPA
- Subject: Mail System Problem
-
- Sorry JOE, your message to SAM@HOSTZ.ARPA lost.
- HOSTZ.ARPA said this:
- .
- End Example
-
- Can my mail be traced?
- Yes, the IP address you mailed from can be traced if you are not careful.
- All mail will show a line in the header listing the IP address that you
- originally telneted from. If the person you are sending mail to doesn't
- know much about IP's and the like, you shouldn't worry too much.
- Furthermore, depending on your the nature of your connection, there are
- different implications. For instance, if you have a direct connection, you
- can be easily traced by your IP address. On the other hand, if you have a
- dial-in connection or service such as AOL, you will not have a defined IP
- address. You will be assigned a temporary one. The only way your mail can
- be traced with this type of connection is to check against the dial in
- service's system logs. The take-home message is that you are safe with this
- type of connection unless you do something really stupid. Finally, the best
- case scenario is a public access terminal with no logging. This type
- connection is untraceable.
- Author's Note: I have found some servers that don't log IP. Read No IP SMTP

-
- What SMTP servers can I use?
- An easy (but hit-or-miss) way to find random SMTP servers is to look at web
- addresses on Yahoo! or another search engine. Universities and government
- agencies are always good choices. Find a URL and telnet to port 25. If you
- get a response, you have located an available server. 95% of servers will
- accept your mail. The others will not allow external mail forwarding for
- security reasons. Always test the server first.

- Check Hunter's List of Usable SMTP Servers. All servers on this list have
- been tested and will work. A hyptertext interface makes it easy to use the
- servers.

- Note: There is no guarantee that the administrators of these servers will
- be happy if you use the servers. I am only acknowledging the existence of
- these servers. For a server that doesn't stamp your IP on the message
- header, read No IP SMTP Server
-
- If you have a telnet client set up as a helper app to your web browser,
- simply click on the name of a server to use the server for direct mail.
- Some links may be slow.

- When I wrote How to Send Fake Mail Using SMTP Servers, I said that your
- messages are traceable by your IP address (it will always be stamped in the
- header). Well, slowly, I am finding systems that don't append your IP to
- the message. You can send messages through this servers, using the
- techniques I described in my SMTP fakemail tutorial, and they are totally
- untraceable. If you have a telnet client set as a helper app to your
- broweser, all you have to do is click on the link below, and you will be
- connected to the respective SMTP server.
-
- DO NOT DO ANYTHING REALLY STUPID WITH THESE SERVERS. If a server was posted
- on this list, but isn't now, don't use it! Don't say that I didn't warn
- you.

- How to find your own IP-Less Severs:
- Finding your own servers that do not append IP to message headers is a
- relatively easy process if you know what to look for. There are many SMTP
- server programs out there. Sometimes you will hit an odd system with an
- unusual server program that you can test by hand. However, the easiest way
- it to look for the more common ones. By far, the easiest to look for is a
- certain older Sendmail version that many systems still use. To find it,
- connect with a server as usual. Examine the welcome text. You are looking
- for a line that looks like the following:
- 220 xxxx.xxxx.xxx Smail3.1.29.1 #15 ready at Mon, 10 Jan 96 12:34 EDT
-
- The important part is the Smail3.1.29.1. If you find a server with this
- number, 3.1.29.1, or another 3.x.x.x number, you have what you are looking
- for.
