I'm not a sendmail guru by any stretch. Probably even more clueless than
most <g>, but I'll chime in anyway. Keeps me humble.
What do you have in your alias file in /etc/sendmail? I have a line that
(use a tab ot separate the above entries)
My MailScanner box is just a gateway so I also added a .forward file in
/root which contains the address to forward to on our internal mail server.
It may be as simple as changing the name of the server to .com instead of
.local though. If that's not in the cards, then I'd look at using
mailertable to define what hosts you forward mail to. Without knowing your
network layout, I'd offer this: The internet facing machine should be named
mail.woodmaclaw.com, and if it just accepts and forwards mail to an internal
host it should have entries in the relay-domain file for what domains it
will accept for and in the mailertable for where to send them. At least
that's how I'm set up and it works for me. Hope this helps...
