Challenge-response is considered harmful. Guaranteed to go to the wrong person every time it receives spam. Causes mail loops when someone with challenge-response emails it. Fundamentally breaks reliable transmission in SMTP. Requires registration to get your email through. Causes mail servers to get listed on RBLs. Nobody in their right mind would consider challenge-response and not expect to get listed as a spewing site and lose all legitimate email in the process. -- Paul Johnson Email and IM (XMPP & Google Talk): [EMAIL PROTECTED] Jabber: Because it's time to move forward http://ursine.ca/Ursine:Jabber -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
