I was wondering if anyone could help me. I'm trying to find some way to filter messages in a qmail-courier system so that the from domain has to match the to or cc domain (don't ask why) to be delivered. I was told maildrop would be able to do the trick. I looked at the docs and tried to come up with a filter, but have no way of testing it yet (and I'm not quite sure if I understand everything). Would any filtering experts out there take a look at this and tell me if it would work? If not, could you point me in the right direction?

Thanks in advance, Jeff Hoover DEFAULT="./Maildir" DEFAULT_DEF="/var/qmail/maildirs" # first get the entire from address if ( /^From: *!.*/ ) { ADDR=getaddr($MATCH2) }

# now we just want the domain

if (($ADDR) =~ /@.*/) { FROM_DOMAIN=$MATCH }

# now compare to see if each to|cc domain matches

foreach /^(To|Cc): .*/ { foreach (getaddr $MATCH) =~ /@.*/ { if ($FROM_DOMAIN eq $MATCH) { cc $DEFAULT } else { # log,return message...do nothing? } } }
