Postmaster notify: Host unknown (Name server: servertest.com: host not found)

[Dean Anderson <dean () av8 com>]

Look. Just got 30 of these.  First international relay. Coincidence that it happened today?  Or is it more likely the 
culprit is on this list?  That is, a malicious antispammer.

Actually, we were probed by someone at dansk telecom a few weeks ago.  From a non-customer machine.  Hmm.
