If ChoiceMail cannot identify a message after checking it against against your Whitelist, Blacklist and any rules you are using, it sends a “registration request” to the sender.

This short email directs the sender to a web page where the sender will be asked for his or her name, email address and reason for contacting you. The sender also will be asked to fill in a code that appears on the screen as a graphic, something a person can do easily but a computer cannot do at all.

This simple process eliminates almost all junk email for two reasons. First, spammers usually use invalid reply addresses and therefore never receive the registration request. Second, spammers depend on automation, and the registration response cannot be automated.

You can turn the registration feature off if you wish. But most of our users love it because it puts the burden of identifying unknown email back where it belongs -- with the sender.
