Re: [TCLUG:10449] Majordomo and Gernal Mailing List Junk

You can probably do this with a nice little sendmail hack.  Have
sendmail check - if the recipient is whoever@wherever.com it should be
passed to a special mailer.  The special mailer could be a shell/C/awk
script that will extract the from=<> from the e-mail and drop that into
a textfile, and then pass the message on to the standard mailer.  The
regular SMTP mailer will take everything on the command line, and the
message as stdin.  After your script runs, it can just pass the message
on to your local delivery agent.  You just need to write a ruleset that
will detect e-mail going to the proper address, and then write a
pseudo-mailer that will do the above.

You could be fancy and add a macro or a hashed map of such e-mail
addresses:
Kemaillist hash /etc/mail/emaillist

and then in sendmail, 
R$+ < @ $=w . >         $: < $(emaillist $1 @ $2 $@ $1 $: @ $) > $1 < @
$2 . >

then define:
Memaillist,       P=/usr/bin/emaillist.sh, F=lsDFMShP, S=10, R=20/40,
                  A=vdeliver $u $h

Alternatively you could edit the source to the local delivery agent
(usually procmail, and the source is VERY ugly - {}'s and ;'s where they
needn't be, and poorly formatted) and hard-code the functionality in. 
We were able to do some nifty things with procmail to get it to deliver
to special /var/spool/mail/mail0...15 subdirectories without much
difficulty.
