Hi,

Yes, after it's received, there are a ton of things that could be done
to block it (including my local RBL). I was hoping for something
preventative.
Eh? I'm afraid I don't get this at all - greylisting and RBL checks in
the MTA before SA even sees it, are the only thing
out there that is even in the realm of preventative measures and you
already know about greylisting.
Are you not aware that once a DATA channel is opened on an SMTP
transaction that you have effectively "received" it?
You're thinking too hard about it. Yes, of course I was talking about
before this message, or the dozens like it, were received in the first
place.
But, putting RBL checks into the MTA is the best way I know to piss off
your users since tag-and-forward is not an option on MTA rbl checking.
That's why we all do our RBL checks in spamassassin.
Look into postscreen and the postscreen_dnsbl_threshold to rank the
DNSBLs to weight them to prevent any single one from rejecting mail.
Regards,
Dave
