I agree. I currently only run one server with a junk folder (as far as I recall), and that is a "pending" folder for mail which has a challenge- response message sent out (not my choice, I'm just paid to do sysadmin work).
sucks to have to do something so useless and crappy. years ago (when the challenge-response idiocy was first starting), i wrote some procmail+perl code so that if the message was a C-R request, procmail would pipe it into my perl script which would extract the confirmation URL and fetch it with lynx or curl or something. i.e. ALL C-R requests were automatically confirmed. my attitude was that if backscattering bastards are going to outsource their spam checking to me just because my address had been used as the sender by some spamming scumbag, then i was going to make sure THEY got all their spam rather than me having to see it or deal with it for them. fortunately, challenge-response was only a short-lived fad, and never became common. most people realised it was just backscatter spam that only made the spam problem worse. i just looked for it now, but can't find it in my procmail scripts directory....I must have deleted it or lost it. i do recall that it was trivial to write as C-R messages tend to be consistent and easily parsed. craig -- craig sanders <cas@taz.net.au>
