One of our readers, William, wrote in this morning to let us know he has been seeing a lot of REJECTED email traffic. It appears to be the result of the reactivation of a defunct RBL that is denying all email traffic.
His suggestion for a quick fix of the problem is to remove the "dun.dnsrbl.net" entry from the list of RBL's used for Anti-Spam protection. He reported to us that he was seeing this as wide-spread starting at 01:15 Pacific, 30 November 2008 and was still continually getting reports from across the nation as of 07:55 Pacific, 30 November 2008.
Please contact us and let us know if you have been experiencing issues with this.

UPDATE: Thanks to everyone for confirming this issue. J.R. wrote in to confirm " This is probably because *.dnsrbl.net is now resolving to 127.0.0.1. Removing this host fixed the issue." Thanks again to everyone for writing in.
