Spoofed NDR issues

04/14/2008 13:05

We've seen a rash of NDR (non-Delivery Response) floods happening to our clients. In all cases, it appears that the spam being NDRed is spoofed, but we are receiving reports from these users that they are being black listed on spam filters.

Is anyone else seeing this problem?

Still getting several of these in My POP email account per day. Appriver seems to have taken care of them in my Exchange mail though.

Also a client with Ninja spam filtering on thier exchange server is complaining of "lot's" of spam getting through and legit messages are now being detected as spam. My only Guess is that as Anti Spam vendors update thier patters to try and detect this latest round of attacks thy are also catching more legitimate emails as spam!
