'''Mailwasher''' is an [email filtering](/source/email_filtering) software for [Windows](/source/Microsoft_Windows) that can detect and delete [spam](/source/Email_spam) from a user's email when it is on the mail server, before being downloaded to the user's computer.

Mailwasher was developed by the [New Zealand{{En dash}}](/source/New_Zealand)<nowiki/>based company Firetrust.  It uses a combination of user defined filters, spam databases and [Bayesian](/source/Bayesian_spam_filtering) filtering.  The filter works on a small portion of each email, and then allows unwanted emails to be directly deleted from the user's [POP3](/source/POP3) inbox, without downloading them to the [email client](/source/email_client) on the user's computer. This approach is intended to prevent the downloading of spam and other messages infected with malware.

There are two versions of the program. The free version can access only a single mail account and does not contain the Bayesian learning filter. The Pro version can access multiple accounts and has additional features.
