After some thought, perhaps I shoud clarify what I am trying to do. I have
looked and looked, and seems most every feature for filtering relies on
.qmail files, or something like procmail. I would like to determine if there
is a way to avoid both of these. Since the machines in question with this
problem are relays (private relays in case you are wondering), there are no
home directories for me to add .qmail files to. Also, since they don't hold
mail locally, with procmail, the path would be:
sender > qmail > procmail > qmail > relay target host
which would signifigantly increase the load required to send each piece of
mail on to it's destination. I don't want to send every piece of mail
through procmail (or similar) if I don't have to.
What would be great would be to have qmail-smtpd catch the HELO or MAIL FROM
address the sender gives (a la badmailfrom) and do something, like perhaps
dump the mail to a local account for further processing, or initiate a
bounce, anything other than just an smtp reject. This way, good mail would
travel clean on through the relay without being subject to any additional
filtering, and only mail matching a bad domain would get handled further.
This may be entirely out of the realm of capability within the parameters I
have described, I'm not sure. It just seems there must be some way to
fanagle qmail itself into reacting to the sender domain. If this answer is
painfully obvious, feel free to slap me, but I'd rather know regardless :)
