Guide Review - Mailblocks - Spam Filtering Service
On the one hand, only mail from authorized senders is allowed entry to your Mailblocks Inbox. New senders get a challenging message (when they reply to the challenge, this sensibly authorizes them for all Mailblocks users), or you authorize them manually.
In the other hand, you hold a bunch (a reasonable 15) disposable email addresses, which can be disabled at will if they receive spam.
While the Mailblocks web interface is slick, fast and offers basic, useful filtering, it still lacks some features: Mailblocks doesn't incorporate secure messaging (using either S/MIME or OpenPGP) and the message editor can't quote text properly in replies.
