[SLL] Multiple domains on postfix/dovecot

[Chuck Kranz]

I have been through that. mynetworks has the "all" (which is the default)
And it seems to transmit. It just seems to want some sort of relay to happen.
The other, NATed node sends when originated from within the lan.
Seems either of them won't send from the internet with out some sort of relay 
provided.
