Situation
3.25.08 - Systems using the decommissioned ORDB (Open Relay
DataBase) service in their SPAM filtering configurations
experience false positives for all IP addresses/hosts both valid
and invalid thus blocking all incoming mail.
Resolution
Remove the 'ordb.org'references from any SPAM
filter configuration lookup.
Additional Information
ORDB.ORG was decommissioned in December of 2006. Some
administrators did not remove the service lookup from their
anti-SPAM filter protocols. When the server(s) for the .org
came online once again March, 25, 2008, they were configured to
return false positives for all IP addresses both valid and invalid,
thus effectively causing all email ... both valid and invalid ...
to be blocked by a firewall/anti-SPAM filter that was still
configured to use the ordb.org query. The intended effect
seemed to be to force the removal of this service by all parties.
