Anger Management

The inimitable White Glenn received one of those obnoxious confirmation-bounces anti-spam software occassionally does these days. As a man of good taste and high ideals, he didn’t like it. How to avoid this problem with our hypothetical $MTP protocol? The only possibility I can see is over analysing all our email — if you get a reply with an In-Response-To: header matching an email you sent, or one whose From: and Subject: match a To:/Subject: you’ve sent.

TMDA does some of this sort of stuff, apparently. Alone, though, it’s just increasing the arms race.

UPDATE 2003/08/26:

Some more on why email challenges suck. A promising comment from that:

Any effective spam remedy must attack one or the other side (or both) of this equation: raise the costs or reduce the technological effectiveness, on the one side, or reduce revenues on the other.
