There are a group of Outlook 2003 clients that connect using POP to SCO servers
that use sendmail. The externally bound email is relayed through the SCO
servers to an Exchange 2003 server, which then passes it off to the spam filter
and out.
If I telnet from any one of the SCO servers to the Exchange 2003 the email will
pass on to gmail, juno, etcetera without problem.
If I send a test email from the Outlook 2003 client it will work on one of the
SCO servers but not the other 2. From the other two I get a return back of,
"Connection refused by aspmx.1.google.com".
My first thought was the SPF record, but I tried the various online SPF tools
and they tell me it's fine. This makes me think that there's something going
on when it passes through the SCO box.
I have checked the sendmail.cf files on each server and the only differences I
see are what I'd expect in as far as the names of the servers.
Anyone out there have experience with mail on SCO, specifically sendmail, that
could share a thought on how to troubleshoot?
