-
- 1) Why does Listserv strip names given to 'subscribe'?
-
- The listings for 'recipients' and 'statistics' requests are compiled by running
- shell scripts. The system strips names for security reasons (we do not want
- backquote characters to be passed to the scripts), and to avoid syntax errors
- (characters like <, > and | may cause problems); the system preserves '-',
- '@' and '.'. The system also converts the wild characters * and ? to #, and /
- to % for security reasons again.
-
- 2) Why does Listserv put 'Comment:' header lines and not the standard
- 'Comments:'?
-
- Listserv prefers to use proprietary header lines because in version 6.0
- configurable headers will be supported. This means that the system will be
- able to carry over header lines from the original sender's message, and these
- may include 'Comments:'
-
- 3) Why does Listserv use the 'From ' address instead of 'From:'?
-
- Primarily for security reasons, i.e. to reduce the likelyhood of forged email.
- It also makes the algorithm easier, it enables peer lists to work, and does
- not have to parse multi-line 'From:' lines to look for the address. The system
- provides the aliases files for dealing with 'From ' addresses that cause
- problems.
-
- 4) Why does Listserv put the list's address in the 'Sender:' header line?
-
- So that error messages sent to this address are properly archived; these
- messages are then sent to the owner. RFC-822 requires that this address is
- the actual account where the mail originated from; the author does not agree
- with this, since this would imply the 'server' account (i.e. the manager
- of the system), and the owner would not see these error messages in this case.
-
- 5) Is Listserv fully RFC-822 compliant?
-
- No. It does not accept addresses in the 'From ' line that contain backquotes
- and wild characters, for security reasons. It also does not support multi-line
- header lines, and uses non-standard header lines. However, it enforces
- "matched-pairs" syntax.
-
- 6) When receiving a news feed, the body of the message contains all the header
- lines, and the distributed message has an empty 'Subject:' field.
-
- You have not set up things properly and the list does not receive the article
- in email format; instead the gateway or news-feed program sends the article in
- a mail message, which is a different case.
-
- 7) The return mails generated by listserv.c and list.c contain two or
- more Errors-To: fields.
-
- Comment out the following line from your sendmail.cf (or whatever have you):
-
- HErrors-To:
-
- 8) What are the relevant files the manager and owners should be periodically
- checking?
-
- a) I check /usr/server/.report.* and /usr/server/lists/*/.report.list on a daily basis.
- b) The various mbox files (/usr/server/mbox, /usr/server/lists/*/mbox) should
- be cleaned periodically.
- c) The /usr/server/mqueue directory should be periodically checked to see
- if there are any files sitting in there waiting to be delivered.
-
- 9) OK, now I installed the software, what do I do next?
-
- Read the README file in this directory.
-
- 10) What does this software do?
-
- OVERVIEW
- This is a system that implements various mailing lists with
- one list server. It is automated, and obliterates the need
- for user intervention and maintenance of multiple aliases of
- the form "list, list-owner, list-request", etc. There is
- support provided for public and private hierarchical
- archives, moderated and non-moderated lists, peer lists,
- peer servers, private lists, address aliasing, news connec-
- tions and gateways, mail queueing, digests, list ownership,
- owner preferences, crash recovery, batch processing, confi-
- gurable headers, regular expressions, and live user connec-
- tions via TCP/IP.
