Bluebottle email

Anyone heard of Bluebottle email? I've just signed up and it seems to be pretty good. It controls spam in the best way I have ever seen... You build a list of allowed senders, and if your name ain't on the list, you ain't gettin' in! When someone does send you an email they receive an automated reply asking them to click on a link to verify their knowledge of you... that done, they are added to you allowed list and you can recieve mail from them! You can of course remove them from the list if you want.

If anyone else uses this or has any thoughts please reply, otherwise check it out at www.bluebottle.com
