[SLL] Multiple domains on postfix/dovecot

[Chuck Kranz]

  What I've got is about the outgoing server. Seems Thunderbird sends
right back itself. If I'm on a dhcp network it's an invalid address.
Specifying an outbound server and getting IMAP to send from there is the goal.
Thanks for all of the good advice. This is one of the best Linux lists around.
