as the lowest MX I scan the mail to see if
it is spam. Then use a transport rule to
forward them on to the destination mail
servers.

I use Spamassassin site wide (using Postfix and transports)
This works great, I had a request from one of the domains
that go through my mail server to have all tagged mail
go to a single account.

postfix do this. So using anything anywhere.
