Hi,
I've got a virtual domain setup with a box dedicated to spam filtering
in front of it, to keep the hungry spam and av checks away from the
mail server itself.
Mail between domains is delivered as expected, but the behaviour I'm
after is one where if the sender domain is not the same as the
recipient domain, and the recipient domain is on the mail server, and
if it hasn't got a header from the spam box; send it through the spam
box first.
This way all local domains' incoming mail would get scanned and avoid
sending mail out through the spam box which is only setup to accept
mail for the domains on the mail server. The reason for this is all
the clean/crap reporting is done on the spam server and I'd like to
have those stats.
I guess something like ( $sender_domain != $recipient_domain ) &&
exists $local_domains{$recipient_domain} then send it on to the
header checks which would check for the spam box header and deliver
appropriately. Ideally these domains wouldn't come from the data
section.
Does anyone know of a way to achieve this (preferably in a way that
doesn't require a rule(s) per domain) or can point me in the right
direction?
