[conspire] Another nail in the C-R coffin

I've always maintained that it's important to protect people's right to
deploy "challenge-response" e-mail systems -- so that the rest of us can
identify them as idiots and globally killfile them and their mailbots.

"Challenge-Response Filtering" on http://linuxmafia.com/kb/Mail/ has a
modest list of procmail recipes for that purpose, though obviously I
need to submit one for Zerospam's X-Mailer header, or start my own
collection of such.

"Challenge-Response" on http://linuxmafia.com/kb/Mail/ (Karsten Self's
essay) summarises the main reasons why C-R is a dumb and actively
harmful move.

I'm afraid that spam has become such a problem that I have resorted to using Zerospam, and as a result, a recent email that you sent me has been quarantined.

If you intended to send me this mail, then please click the link below to add yourself to my trusted address list.  It only takes a few seconds, and you only have to do this once.

I'm sorry for any inconvenience caused.
