Mailwasher is an anti-spam and email filtering program that helps protect users from malicious and unsolicited emails. It is designed to be used in conjunction with a regular email application, such as Outlook, Thunderbird, or Apple Mail, to provide an extra layer of protection. It allows users to preview, monitor, and filter incoming emails before they ever reach the inbox. It can detect and block emails containing viruses, phishing attempts, spam, and other unwanted content. Additionally, it can be configured to automatically delete emails from the server, allowing users to save disk space and keep their inboxes clean. Mailwasher also features a whitelist, which allows users to whitelist certain senders so their emails will always get through, and a blacklist, which can be used to block emails from known spam sources.
Discontinued The project is no longer being developed. The latest version, 0.99.9, released in August 2007, can still be downloaded from SourceForge.
