Ben,
Do you have, in the SMTP (or Security, cannot remember V4.0x too well), the
'Refuse Null Sender' enabled? If you do, disable, Apply/Save then stop/start
SMTP service. Now you (and the sender) will get normal bounce messages that
can give you needed information.

Subject: [IMail Forum] tracking blocked mail
We run multiple domains on Imail 4.07, generally without problems. =
However, we recently ran into someone who cannot send mail to any =
mailbox in our primary domain. That is, mail they send to mail (or my =
co-workers) with disappear without even an error message. It looks to =
me like the mail is being blocked somewhere, but I can't find where.
This customer uses Exchange 5.5, but they don't have any blocking set up =
at their server. They can successfully send mail to other domains that =
we host on the same mail server, just not our domain. So, for example, =
their mail won't reach me at [EMAIL PROTECTED]
Does anyone have an idea how to trace the blocking for this? They use =
the Internet Mail Connector with their Exchange to retreive mail from an =
ISP. I wonder if the ISP is blocking the mail, but they're not very =
cooperative in this investigation.
Thanks,
Ben Bednarz
