Thn enclosed example of how not to filter spam is offered for those who might want to preemptively add accuspam.com or downloadfast.com to their blacklists. It is also a classic example of what is wrong with the MUA filtering tactics Robert Brown advocates. I certainly did not try to contact anyone at 3dize.com. A few readers of this mailing list might recall that Shelby H. Moore III and I don't see eye to eye. I do not know what the From: header of inanbe@xxxxxxxxx is about. Perhaps it was forged. Or perhaps someone at that address wired a subscription to this mailing list through an unusually braindea) challenge/response spam filter at DownloadFAST.com. If so, the Secretariat should blacklist accuspam.com and/or downloadfast.com from subscriptions to IETF mailing lists. (It would need to be unusually braindead to send me the challenge instead of the envelope sender.)
