[David Lucas <david@xxxxxxxxxxxxxxxx>]

My email was not even open at this time.

Apr 22 10:27:56 www sendmail[20023]: g3MFRnd20021: SYSERR(root): 
dc.k.yetiservices.com. config error: mail loops back to me (MX problem?)
Apr 22 10:27:56 www sendmail[20024]: NOQUEUE: www.yetiservices.com 
[66.77.173.56] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA

The returned email headers are as follows:  The user tags@xxxxxxxxxx is 
also me.  I did not send this.  It had a virus in it.
How is this person using my server?
