Actually, this is referred to as "Greylisting" which is used to verify whether or not a message sent to someone is spam or not; also, I believe that there have been numerous attempts in the past to define exactly whose responsibility it is to make sure a message goes only to an intended destination (like only to an e-mail reflector, which I believe was what you intended in you first message), so I won't go into that here.

Why should I click on a strange link in an unexpected mail which could be anything? 73 Dave G3YMC On 5 Oct 2011 at 16:56, Jim Brown wrote: > My email server is protected by "challenge and response" anti-spam > service provided by my website and email host.
