Dustin

I have the same problem with my server and the symptoms are identical. I
ended up with thousands of email in the spool going to aol and Yahoo.
There are already multiple posting under  "[IMail Forum] HELP - Imail
Problem" about my problem. I've been telling everyone that I've triple
checked the SMTP relay and the IP is set properly. I'm not so sure this
is just a co-incident that our server was compromised at the same time.
The server has been working for more than 2 years and I know the Ip
relay is set correctly. 

In situation like this I really wish that other people experience the
same thing. I suspect it is a hack or problem with IMAIL because the
mail mainly goes to yahoo or aol. If a spammer took control a server
they would send to everywhere not just aol and yahoo right?

Regards
Bo Wee

Scott,

Ok the Ip is not listed in our Allowed addresses and Imail is set to
Relay fo Adresses. We looked over the logs for the Ip and found this,
could the problem be that the are possible going though one of our users
systems so that when it communicates with our server it lets the mail go
since it is an Ip that is allowed??

Here is a log snip from last night:

Ah, I missed the "to AOL" part.

That means that this is definitely NOT a dictionary attack.  It is just
a 
standard hijacking of your mailserver by a spammer.

In this case, you need to:

[1] Check to see what your anti-relay settings are; make sure they are 
"Relay for Addresses" or "No Mail Relay".
[2] Check your log files to see the IP address that the E-mail came
from, 
and see if that IP is authorized
[3] Check your log files to see if the user authenticated.

The interesting part here is that you seem sure that this is someone
that 
you did not authorize to use your server -- why do you think that?
