I aggressively report spam here, including NDR redirects. Spammers are using servers that send NDRs almost as effectively as open relays. It's unfortunate: I'd like to be able to use NDRs as intended in the RFC, but my system doesn't generate them. If it accepts them, and then determines them to be spam, it either quarantines or deletes them. I'm not trying to say my way is better than anybody else's, that's just how I've decided to deal with it.

(that's not a trick question :-) ) We currently try to send the 49 spammy ones. In our case the 49 do not impact the performance of the mail gateway. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of East, Bill Sent: Thursday, 20 December 2007 10:03 To: Exchange Discussions Subject: Email philosophy 101 - Spam NDRs Let's say we get 1000 messages with invalid addresses into our spam filter. 950 of them will get caught as spam if we filter them. 49 slip past the filter but shouldn't have. They're directory harvesting messages, invalid return addresses, and valid return addresses of people who didn't send the spam. 1 is a message from one of our customers asking for directions, that he fat-fingered to MemmerService Should we send NDRs on the 49 spammy ones so that the customer gets his NDR? Or should we silently drop his message so that we're not sending 49 NDRs that we shouldn't?
