I believe that is my problem. This server is not on the public net here.
It's not a matter of having the network provider adding an MX record, I
can have that done quickly (I'm in charge of that), its that if I add an
MX record it's not going to point to a mail server, and that is
something my network admin won't have/allow, if only for her FUD about
While "harrisburgpa.gov" has a public zone file, it does not have an MX
record or an A record for "mail" or other such name. Only "www" as those
servers are the only ones exposed on the public net.
So, how do I turn sendmail into a relay for outgoing mail? Or whatever
that is called. :)
