In the dns for foo.dom
$ORIGIN foo.dom
MX 10 primary.foo.dom.
MX 20 secondary.bar.dom.
Does not matter on which network the servers are.

1: Don't tell the SMS foo.dom is local, i.e. don't put it in Cw
2: It just tries once in a while. Or the PMS could issue an ETRN (Look for
etrn.pl, in sendmail/contrib, I think it is)
and ask the SMS to start sending to foo.dom.
3: It will just look in the DNS. for the lowest MX working. It won't be
sending to itself or any higher numbered MX.

If you are missing the connection too often, perhaps you need a backup
server :->
