Can't lyris be configured to listen/use another port? It sounds like Lyris
wants to the the front end, and the mail server to be the backend, which is
just the opposite from what we want, well, you anyway, since I plan to have
Lyris on its own machine forwarding all of its outbound to Imail, and Imail
relaying inbound to Lyris.

Well, that's where secondary MX's come in.

The remote MTA's should/will switch to the 2ndary MX's, non?

yep, I understood that Imail listens on all ip addresses.
My only thought is my approach: use two machines.
