ORDB RBL is closing down

Quote from http://www.ordb.org/news/?id=38:

We regret to inform you that ORDB.org, at the ripe age of five and a half, is shutting down. It’s been a case of a long goodbye as very little work has gone into maintaining ORDB for a while.
We encourage system owners to remove ORDB checks from their mailers immediately and start investigating alternative methods of spam filtering.

So, if you use relays.ordb.org in exim RBL ACL, or ORDB-RBL in the MailScanner “Spam List” setting, remove it asap.Note: We do not configure either exim or MailScanner to use this RBL when we perform the MailScanner Sevice package work
