Yes, it's odd that only one sending domain is affected.

No, looks fine to me. However, note that the connection from the sending
machine is cleanly closed with a QUIT : this is different from what the
sender thought was going on, because it failed to see the "250 OK
id=1CtodJ-0003d4-IK" response and never said QUIT because the connection
had been closed!
I think your firewall is lying to you. If it has any SMTP fux-up features,
turn them all off.
