ordb

The problem is that over 220,000 unique IP addresses queried us in a
15 second pcap file I just looked at. So there are an enormous number
of people who have not fixed their mail systems to stop using ORDB.

Folks, if you run a mail server or know someone who does... have them
double and triple check the RBL's they are using.
A best practice would be to review logs frequently enough that the admin
would catch dnsbl's that have been retired in a Not Good Way (tm)
My idea of frequent and someone elses may differ, so please, at *least*
once a month. Check for dnsbl failures.
