I don't understand this reasoning. If Kerio is inadequate, why use it at all? If Postfix lacks some feature Kerio has, perhaps you need to concentrate on getting Kerio to work as you need it.

To fix this, ensure that Postfix is not listening on 127.0.0.1, and Kerio contacts Postfix using the external IP address. http://www.postfix.org/postconf.5.html#inet_interfaces > I've tried using a separate IP for each STMP server and explicitly > binding SMTP to separate addresses in master.cf but I still get > the same error.

Rethink the structure. Simplify. Choose one or the other MTA; make it do everything you need. -- Offlist mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header
