I have succesfully setup qmail on a RedHat 6.0 server. I have had meetings
with my boss and he wants everyone in my company to have emaill access, but
not internet access. I have been thinking on how to do this, and I have a
few ideas, but I am not quite sure of which way to do this.

One viable (but not exactly elegant) approach is to simply block all
incoming and outgoing traffic *not* from/to the mail server at the router.
Then to help secure the mail server, block all traffic to/from its address
except for necessary traffic (smtp, pop3, name lookups, etc.)
Quick and dirty, but it works. ; )
