I have no idea how on Postfix, but this could help you too Scott Lavoie.
If there are multiple exchange backends for postfix/spamasassin
gateway ... how could one validate that users exists, given that you
only have a list of valid users for some of the exchange servers and
the mailahead/milterahead/smtp are not an option?
Don't think you're hijacking the thread -- you just stated exactly, what
I mentioned in my previous post.
The only real problem, validating recipients at the front MX, based on
the data in the backend Exchange servers. Everything else is not a
problem, even though managing a Linux server might seem to be one from
the point of view of a Windows admin... ;)
This can be done VERY easily and safely with milter-ahead
(Sendmail/Postfix).
If you don't need the nifty extras milter-ahead supplies, Postfix has
built in rcpt adddress verification which imo, works well and is also
well documented
