Ditto. If the person using CRAP posts a question and I spend the time
crafting a response, I'm sure as hell not going to jump through hoops.
Whats worse are the morons that send you private mail first, and you
respond and get a challenge. They should at LEAST auto-whitelist
everyone they send mail TO. These people go in my killfile. The havaoc
it causes to autoresponders like ticketing systems (support@) can be
QUITE severe - mail looping and such.
