news2mail - Channel script to gateway news into e-mails

NAME

       news2mail - Channel script to gateway news into e-mails

SYNOPSIS

       news2mail

DESCRIPTION

       news2mail runs as a channel process underneath innd.  It is set up as
       channel feed in newsfeeds, with different mailing-lists as funnel
       entries pointing to it (see below); news2mail expects the token of an
       article followed by a sequence of list names.

       news2mail uses the configuration file pathetc/news2mail.cf to map
       mailing-list names to e-mail addresses.  news2mail causes sendmail to
       queue the messages for later delivery (to avoid DOS attacks by mass
       postings).  You must run "sendmail -q" periodically to get the queue
       processed.

CONFIGURATION FILE

The configuration file format is simple: comments (starting with a
hash sign "#") and blank lines are ignored. All other lines have two
or three fields on them. The first is the list name and is what innd
uses (i.e. the site field of the entry in the newsfeeds file). The
second field is the actual e-mail address to send the article to. The
third field is optional: it sets the envelope-from address (for
instance a list member’s address; if not set, it defaults to the "news"
user).

In e-mail messages, the To: header will have the mailing-list address
(i.e. the second field). Besides, news2mail strips most article
headers from the article before mailing.

In newsfeeds, the channel feed should look like:

news2mail!:!*:Ac,Tc,Wn*:<pathbin>/news2mail

and for each mailing-list, you only have to add to newsfeeds an entry
list like:

list-big-red-ants/lists.ucsd.edu:!*,rec.pets.red-ants:Ap,Tm:news2mail!

Please note the use of "Ap" and the exclusion of the list owner domain
to protect the list from feeding back new arrivals from the list. The
site name used in the newfeeds entry for a mailing-list (above
"list-big-red-ants") must be the same as the first field in an entry in
news2mail.cf. For instance:

# Newsfeeds-name List-to-address [List-sender-address]
list-big-red-ants big-red-ants@lists.ucsd.edu news+big-red-ants@local.news.server.org

FILES

       pathbin/news2mail
           The Perl program itself used to gateway news into e-mails.

       pathetc/news2mail.cf
           The configuration file which specifies the mapping to use for
           gatewaying.

BUGS

       The news2mail program is set up as a funneled channel in newsfeeds,
       implying multiple matches should be handled as one - and multiple
       matching funneled feeds will result in a single call to the script.
       Therefore, since only one mail is sent, crossposts are not currently
       properly handled as for the envelope-from address (which then defaults
       to the "news" user).

HISTORY

       news2mail was written by Brian Kantor in 1998.  This man page was
       written by James Brister and converted to POD by Julien Elie.  The
       third optional field in news2mail.cf was added by D. Stussy in 2008.
