[Greylist-users] another reason to hate challenge response

[Christopher Baker]

Today I got my first of five what you may call "challenge-response spams."
I got five of them, basically at the same time from the same address.

By now, we are all probably familiar with virus scanner spams. These are
messages sent by virus scanners automatically which say: "You sent us a
virus. Your message has not been delivered." It seems as though the
virus scanner companies got wise to this problem. I don't see many of
those anymore.

Challenge-response spams are easily the best reason not to use challenge
response as a method for combatting spam. Perhaps, many users and other
companies will get wise to this. Challenge-response has always been a
bad idea. Hopefully, this will kill it.
