sendmail question

[Robert Meyer]

HMMM... This looks like a job for PROCMAIL!!  Do you think that I'd remember
the syntax for 'from' line filtering?!  NOOOO!!! Of course not!  :-)

It's a really easy thing to to. The next pile of drivel comes from me reading
the man pages for 'procmail' and 'procmailex' and trying to cobble something
together from the mish-mash my brain makes of things like this...

First, put the next line in your '.forward' file for the user that would
normally recieve the mail that you're trying to filter:
|IFS=' '&&p=/usr/bin/procmail&&test -f $p&&exec $p -Yf-||exit 75 #YOUR_USERNAME

Next, make a '.procmailrc' file that contains something like:
PATH=/bin:/usr/bin:/usr/bin
MAILDIR=$HOME/Mail      #you'd better make sure it exists
DEFAULT=$MAILDIR/mbox   #completely optional
LOGFILE=$MAILDIR/from   #recommended                                     
:0
* ^From.*wiseguy at adelphia.com
{
:0 c
   ! darin at nflug.org
}                                                                 

Now, if you're trying to do it on a global basis, there is a hack in the
procmail man page that tells how to hack it into the sendmail rules.  If you're
using 'qmail', then you're on your own on how to implement...

Hope this helps...

Cheers!

Bob
