Bill, there is no problem if you declare your 2 servers like valid MX in =
your=20
DNS. You can have multiple MX for a domain. Maybe your "front end" server=
=20
with a preference value of 10 and your internal server with 20.
But your internal server must have a public ip address. If you not have a=
=20
public ip address, you can configure your fron-end server at gateway for=20
internal server ("DefaultSMTPGateways" option in server.tab)
Now, whats the problem ?
