Severity: important

I am running postfix with postgrey for graylisting and I'm getting tons
of :

   Oct 31 16:20:21 hermes postfix/smtpd[6778]: NOQUEUE: reject: RCPT from 
$HOST[$IP]: 450 4.2.0 <>: Sender address rejected: Server unavailable.  Try 
again later.; from=<> to=<[EMAIL PROTECTED]> proto=ESMTP  helo=<$HOST>

I am getting too many of those with an zero-length from and with
abqnm$RANDOM_STRING as the originator, so I suspect it is some
clever antispam or open relay testing tool.  At any rate, it is
generating waay too much noise.

Thanks,
florin
