[SLL] Multiple domains on postfix/dovecot

[Chuck Kranz]

I've been googling to get the postfix.org docs for quite a while.
I don't get a clear, for my understanding, answer. It could be my level of
understanding. :-)
I have another CentOS 5.2 node that works from its lan. It has NAT so it will
only send e-mails when sent from the local lan. If you IMAP in from
outside you can read your e-mail but get a Relay Denied error when sending.
  The first node I mentioned is a single address server so it should be
accessable from anywhere via dovecot IMAP SSL.
  I'll try some virtual stuff. I would like to understand what I'm doing
and was hoping for some past experience from the sages.
I have used virtual for some e-mail list configs for majoedomo before.
Thanks for the good advice.
