Sorry, NO PTR RECORD FOR ZEMOS.NET
You ain't GETTING IN! PERIOD!
Looking at this log, something is unclear to me. Are you connecting to the
comcast.net server that's connected to you, or are you connecting to a
query-returned MX for zemos.net? Your manual tests in your later response to
Markus indicate that you're checking against zemos.net, but that's not
explicit here. In fact, I see no mention of zemos.net in the WSCAP log other
than in my address.
What exact DNS queries are you making, what connections are you opening, and
what commands are you sending? I'm not about to tell all of the other
zemos.net MX operators to log SMTP transactions to debug your broken
software. If you're connecting to the comcast.net server in an attempt to
verify the return path, that's WRONG! If it accepted mail for zemos.net, it
would be an open relay.
