Expert Review - Spamihilator 1.6 - Free Spam Filter

Using Spamihilator is a pleasant experience.

Not overcrowded with features and settings but equipped with a neat interface, Spamihilator filters spam before it even reaches your email Inbox.

It does so flexibly by working as a POP or IMAP proxy. (You can even use Spamihilator to access an IMAP account using POP and vice versa.)

How Spamihilator Works

Of course, it's easy to browse and recover accidentally deleted messages from Spamihilator's "Recycle bin". After you have trained the Bayesian filtering a bit via the easy to use "Training Area", this will hardly be necessary, though. Using its Bayesian filter and, optionally, the DCC (Distributed Checksum Clearinghouse), a real-time registry of known spam, Spamihilator will detect most spam automatically while leaving good mail alone.

Spamihilator's Shortcomings

It a pity that Spamihilator cannot mark detected spam for further filtering in the email client. More than two categories of mail for automatic classification would be nice, too.
