smtp problem

I can send but not receive any email. Nothing I send to
my domain ends up in the drop directory. But also I do
not get any undeliverable errors on the senders. I also
don't see anything in either the event viewer or iis &
smtp log files. If I manually move something to the drop
directory it does show up in my email client and sending
from the client works.

Does anyone know what the problem is or how I can figure
this out?

This question would be better handled by our Exchange newsgroup:
