But you don't have to run Amavis on a different host, you can run it on
the same host. Or you can use a network client like the amavis equivalent
of spamc to have amavis scan the email remotely. You may need to write
one if it doesn't exist already. It only has to attempt to send the
messaage by SMTP to Amavis and return an error if Amavis refuses the
message.

Cheers, Chris.
