Let's see:
Possible problems include a DNS problem, firewall problem, or IMail configuration.
I'd rule out IMail configuration, since it will see "@mail.domain.com" or
"@domain.com" regarless of where the server is (unless the firewall mucks with the
SMTP data).
DNS should be ruled out as well. If the DNS entries allow the mail to get to the
server in front of the firewall, everything is fine (unless the firewall mucks with
the IPs).
Therefore, I'd guess a firewall problem.
You should check to see exactly what is happening. Is remote mail server connecting
to the IMail server? You can check the logs to make sure. Where is the bounce coming
from, IMail or the remote mail server?

That would suggest an IMail issue. Do you have "mail.your_domain.com" set up in IMail
as an alias?
You can try telneting to your mail server, and try sending an E-mail manually to
"[EMAIL PROTECTED]" and "[EMAIL PROTECTED]" and see if IMail reacts
different or not. That will also help track down the problem.
