There has been heated debate on comp.mail.misc about C/R systems. There is a "Fighting email spam and anti-UBE pointers" posting which is posted to comp.mail.misc, comp.answers, news.answers 2 times a month. Excerpt: "Challenge-Response system is based on false assumption that sender's address can be used for authentication. It cannot and thus any C-R system will contribute nothing else by amplifying the spam problem." -- Chris. ====== -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
