I could be wrong, but I believe comcast blocks incomming (from outside
networks) port 25 connections, in an attempt to prevent spam, and rogue
machines from becomming open relaying spam machines. I can telnet to
your box, but would explain why your comcast(their mail servers are not
on the same networks as their cable customers), and gmail fail. It
would seem like they're trying to connect to your secondary mail server
mail.mackproductions.com. Which doesn't appear to be setup to relay
mail to t0e.org... Nor would it be able to even if it was... just a
thought. Like I said previously... my assumption that comcast blocks
incomming port 25 could be wrong. Would need to see the full email
headers to tell for sure.
