The easiest way to do this is with a postfix address resolution daemon.
You can just use postfix.PostfixTCPMapServer to do it.

It will be something along the lines of:

class AddressResolverFactory(protocol.ServerFactory):
    protocol = postfix.PostfixTCPMapServer

    def get(self, emailaddress):
        if doesnotmatchpattern(emailaddress):
            return None

        return transform(emailaddress)

reactor.listenTCP(12345, AddressResolverFactory())

Then you just throw all the email addresses at it from postfix like so:

virtual_alias_maps = tcp:
virtual_mailbox_maps = tcp:
