MailWasher Pro is an advanced anti-spam and email filtering software developed by the New Zealand-based company Firetrust. Unlike traditional email security programs or built-in filters that clean your inbox after messages arrive, MailWasher Pro lets you preview and delete emails directly on the mail server before they ever reach your computer or email client. Core Functionality
Server-Level Screening: It fetches a small portion of each email from your POP3 or IMAP server, allowing you to intercept spam, phishing scams, and malware safely.
Safe Previews: It displays incoming emails in a plain-text pane or controlled HTML format, safely neutralizing hidden scripts, viruses, or tracker images that notify spammers you opened the mail.
Pre-Inbox Deletion: You select and purge junk mail with one click, ensuring your desktop email client (such as Microsoft Outlook or Mozilla Thunderbird) only downloads clean, legitimate messages. Key Features
Intelligent Filters: Uses a combination of user-defined custom filters, real-time blackhole lists (RBLs), and a self-learning Bayesian filter that adapts to what you consider spam based on thumbs-up/thumbs-down feedback.
Friendslist & Blacklist: Allows you to easily whitelist trusted contacts or permanently block specific senders.
Searchable Recycle Bin: Caches deleted emails on your local system, allowing you to restore any message accidentally wiped from the server.
Multi-Account Support: The Pro version lets you manage an unlimited number of active email addresses simultaneously under a single sidebar interface. Pricing and Availability
The software operates primarily on Microsoft Windows (including Windows 10 and 11). While a limited MailWasher Free version exists for a single email account (lacking the recycle bin and smart learning filters), MailWasher Pro is offered as a paid service starting at US$34.95 for a 3-computer license, which includes a 30-day fully functional free trial.
