eclean

Finally, a top of the line defense against spammers. First, EClean helps you to avoid being sent unsolicited E-mail messages.

Second, EClean (as a pre-mail client) authenticates and "quarantines" your legitimate E-mail, giving you the option of deleting UCEs before they get in your inbox. EClean's smart enough to learn... it does not rely on users to maintain keyword lists or blacklists... nor does it use new technologies like heuristics or content profiling. You are a few clicks and a short setup from a spam free workspace.
