Firetrust

Firetrust is a New Zealand-based developer that has concentrated for more than two decades on a single mission: stopping spam, phishing and malicious mail before it ever reaches the user’s inbox. The company’s compact product line is built around the MailWasher engine, a pre-filter that sits between the mail server and the local client, letting subscribers inspect every message in plain text on the server first. Both the freeware MailWasher and the paid MailWasher Pro retrieve headers and the first few lines of each message, apply Bayesian learning, RBL checks and custom blacklists, then let the user delete, bounce or whitelist mail with one click; the Pro release adds unlimited accounts, fast batch filtering, SSL/TLS support and server-side automation so entire families or small-business domains can be scrubbed unattended. Because no attachments are opened locally and no images are pre-fetched, ransomware, tracking pixels and zero-day exploits are neutralised before they reach Outlook, Thunderbird or any mobile app. Typical use cases range from consumers who want a quiet inbox to SOHO owners who need to protect staff mailboxes without maintaining a full gateway appliance. Firetrust keeps the footprint light, updates rule sets several times a day, and offers portable and Windows editions that coexist with any antivirus stack. Both MailWasher variants are available for free on get.nero.com, delivered through trusted Windows package sources such as winget, always installing the newest build and allowing batch installation alongside other trusted applications.
