Mailwasher
From Wikipedia, the free encyclopedia
Mailwasher is a popular e-mail filtering software for Windows, Unix, and Macintosh systems intended to detect and delete spam from a user's server account before it is downloaded to the user's computer system. This approach avoids a number of potential pitfalls typically encountered when analysing email messages within the email client, especially if malware is included in the spam message.
Mailwasher was developed by 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.
