Mailwasher
From Wikipedia, the free encyclopedia
Mailwasher is an e-mail filtering software for Windows and Macintosh systems for reducing spam from a user's inbox. It comes from the New Zealand based company Firetrust. It uses a combination of user defined filters, spam databases and Bayesian filtering. The filter works on the user's POP3 inbox, so unwanted messages can be deleted before they are downloaded to the e-mail client on the user's computer.
There are two versions of the program. The free version can only access a single mail account and does not contain the Bayesian learning filter. The Pro version can access multiple accounts and has extra features.
