Valid email rejected by Reputation or RBL lookup – Websense

“relays.ordb.org” was a popular RBL that went out of service in December 2006.  It returned to service March 3, 2008.  Its return to service can and has caused significant problems because IP Addresses listed in their RBL can be outdated, which affects the performance of security devices that utilize RBLs.
