It may be that someone is using a return address on your domain (either a
real one or a fake one). We have a spammer that has occasionally been
using a fake return address on one of our domains for about 6 months now.

An AOL mail server is connecting to your mail server. You can verify that
it really is AOL by doing a reverse DNS lookup (which could be fake, but
they'd likely get into serious trouble if they did that).

This means that AOL's mail server is sending you an E-mail from "<>". That
could be a return receipt for one of your users, or it could be a bounce
message, or something similar. But your system is refusing it, which it
isn't supposed to do. You need to uncheck the "Refuse NULL <> Senders"
option in IMail Administrator.
