DESCRIPTION¶
The
mailpost program reads a properly formatted e-mail message from stdin
and feeds it to
inews for posting to a news server.
newsgroups
is a whitespace-separated list of group names to which to post the article (at
least one newsgroup must be specified).
Before feeding the article to
inews, it checks that the article has not
been seen before, and it changes some headers (cleans up some address headers,
removes X-Trace: and X-Complaints-To:, and puts "X-" in front of
unknown headers).
If the article has been seen before (
mailpost records the Message-ID of
each article it handles), then the article will be dropped with a non-zero
error status. Other errors will cause the article to be mailed to the
newsmaster (selected at configure time and defaulting to "usenet").
Normally,
mailpost is run by
sendmail(8) via an alias entry:
local-mail-wreck-bikes: "|<pathbin in inn.conf>/mailpost
-b /var/tmp -d local local.mail.rec.bicycles.racing"
Instead of
/var/tmp, the mail spool directory can be specified, or any
other directory where the
mailpost process has write access.
OPTIONS¶
- -a addr
- If the -a flag is used, the value given is added to
the article as an Approved: header.
- -b database
- If the -b flag is used, then it defines the location
of the database used to store the Message-IDs of articles sent on. This is
to prevent articles looping around if a news-to-mail gateway sends them
back here. This option may be required if the mailpost process does
not have write access to the news temporary directory. The default value
is pathtmp as set in inn.conf.
- -c wait-time
- The -c flag indicates a length of time to sleep
before posting. If duplicate messages are received in this interval (by
any instance of mailpost using the same database), the article is
only posted once, but with Newsgroups: header modified to crosspost the
article to all indicated groups. The units for wait-time are
seconds; a reasonable value may be anywhere from tens to hundreds of
seconds, or even higher, depending on how long mail can be delayed on its
way to your system.
- -d distribution
- If the -d flag is used, the value given is added to
the article as a Distribution: header.
- -f addr
- The -f flag is a synonym for the -r
flag.
- -h
- Print usage information and exit.
- -m mailing-list
- If the -m flag is used, the value given is added to
the article in a Mailing-List: header, if such a header doesn't already
exist.
- -n
- If the -n flag is used, neither an article is posted
nor a mail is sent in case an error occurs. Everything is written to the
standard output.
- -o output-command
- Specifies the program to which the resulting article
processed by mailpost should be sent. For debugging purpose,
"-o cat" can be used. The default value is "inews -S
-h".
- -p port
- Specifies the port on which nnrpd is listening, used
for article posting. If given, -p is passed along to
inews.
- -r addr
- A heuristic is used to determine a reasonable value for the
Path: header. The -r flag indicates what to use if no other value
can be determined.
- -x header[:header...]
- A colon-separated list of additional headers which should
be treated as known headers; these headers will be passed through to
inews without having "X-" prepended.
Known headers are:
Approved
Content-*
Date
Distribution
From
Mailing-List
Message-ID
MIME-*
References
Return-Path
Sender
Subject
FILES¶
- pathbin/mailpost
- The Perl script itself used to feed an e-mail message to a
newsgroup.
- pathtmp/mailpost-msgid.dir and
pathtmp/mailpost-msgid.pag
- The default database files which record previously seen
Message-IDs.
