I just found out about this problem a couple of days ago, when we were
trying to get a poorly set up mail server (not IMail) to get mail to our
server. We tried having them send to our IP address; user@[127.0.0.1] is a
valid E-mail address, and should be sent to 127.0.0.1 (of course, you would
substitute a real IP here). IMail chokes on this -- it knows enough that
it should send to that IP address, but (at least in our case) didn't know
enough that that IP address was the same one it was answering on.
The result was an "almost mail loop" -- IMail detected the loop after
seeing the E-mail 5 times, and stopped it.

Yes, it looks that way.

You have to wait for it to get killed automatically. It might be possible
to add a domain named "[127.0.0.1]", to fool IMail, although I haven't
tried that.

This was looped on your server, but you should have only received 1 copy of it.
It may be that they are continuing to re-test you (intentionally or not).
