news2mail - Channel script to gateway news into e-mails
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
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:
and for each mailing-list, you only have to add to newsfeeds an entry list
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:
The Perl program itself used to gateway news into e-mails.
The configuration file which specifies the mapping to use for gatewaying.
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).
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.
