I am having some problems trying to configure MMDF on a SCO Openserver 5.0.7
system. Everything I have read indicated that it is simply a matter of
running the mail configuration program, but that only seem to get part of
the system working. Here is our configuration:

INTERNET ------ Linux Firewall/Mail server -------- SCO Box & All machine in
our domain

I am only interested in setting up the SCO box to send messages, not receive
them.

The way it is currently set up is such that it can send email messages to
any machine within our domain, but it cannot send email to any system
outside our firewall. The box has Internet access as it can browse the web
no problem at all.

Any suggestions?
