Author 550 5.1.1 unknown or illegal alias

I have a Server2003, IIS6 set up with SMTP to basically just allow email
through asp pages. I have the relay restricted to my internal dns server. I
have it set to log, but the log file is empty. Over the holiday weekend, I
(as webmaster) received about 6 emails informing me of the above messages.
It appears I'm being used as a relay? Maybe? But, how can I tell if it's
not logging and/or I have relay turned off?

Here's an example of two emails:
<barryp@nc.rr.com>
(reason: 550 5.1.1 unknown or illegal alias: barryp@nc.rr.com)
<calicos3@nc.rr.com>
(reason: 550 5.1.1 unknown or illegal alias: calicos3@nc.rr.com)
lots more.....

and

--AOL Postmaster
----- The following addresses had permanent fatal errors -----
<cscott@aol.com>
<danichol@aol.com>
lots more.....


Any help appreciated...
