"Email blocked by ORDB" ORDB gone amuck

[UpAllNight]

For the last 7-10 days we have observed ORDB incorrectly blocking incoming mail from valid sources as well as the spam. It's blocking mail from sources such as authorize.net as an example. It seems to be intermittent even over the course of just a few hours... blocking, not blocking, and then blocking again. Is anyone else observing this?

I'm running SpamBlocker 2.

For now, I'm going to disable ORDB in SpamBlocker but would like to figure out why ORDB is doing this.

Thanks,
David

SORBS too

It's actually happening with SORBS too:

2006-08-31 15:08:20 H=mailfilter.dcsdk12.org (fram.dcsdk12.org) [205.169.165.62] F=<[email protected]> rejected RCPT <[email protected]>: Email blocked by ORDB

2006-08-31 15:11:01 H=mailfilter.dcsdk12.org (fram.dcsdk12.org) [205.169.165.62] F=<[email protected]> rejected RCPT <[email protected]>: Email blocked by SORBS

I just tried doing a Spam Databse Lookup at dnsstuff.com on the 205.169.165.62 IP and there were no positivies on the IP for ORDB SORBS or any of the other lists!
