Curious if others are seeing this trend too.

Increasingly we are rejecting a lot of mail with just basic sendmail 
check_mail "domain does not exist" rule. What is the point of this kind 
of thing? Is this a new dumb virus? Why doesn't it make up an aol 
address? Is it about spam, or dns, perhaps.

Here's a small sample of the rejected domains:

> tgnemnekyvrd at
> thc at
> tjredstart at
> tkiac at
> tmolar at
> tnjevdfwpp at
> tocgpf at

They are mostly unique, and seem to be bots.
