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.
