Ok everyone.  I may regret this.  Here are two lines out of my maillog.

My customer is cs@xxxxxxxxxxx  adelphia.net has nothing to do with me.  No 
customers there.
He did not send anything here.  We were out at dinner.
The DNS is being provided by register.com
The ip points at my server
The mx record says:  cdbyrd.net hi cdbyrd.net

This has been working fine for over a year.
This only started happening in the last couple of months.  (Like since OS2)



Oh, here is another.  Notice the sender is the same ip but different 
company.  This one is for an ezine, and he did not reply to it.

I do have entries for a couple of other senders.  NO cs@xxxxxxxxxx is not 
sending anything in either case.  I have had about 6 of these on Friday.  5 
to cs@xxxxxxxxxx and one to tags@xxxxxxxxxx (I get this one - I never send 
on it - it was an accident when used).
