So there is no way to "flag" incoming messages that they arrives on a
certain interface and process the sending based on that flag? Reason I'd
like it that way is that I would like to be able to use the same spam
filtering mechanism already in place.

How would I run a second instance of postfix? I assume the second postfix
instance require seperate config directory (/etc/postfix), queue directory
(/var/spool/postfix), what else?
