What Spamihilator is
Spamihilator is a free Windows program that filters incoming unsolicited email between the Internet and an email client. Its Learning Filter uses Bayesian filtering, and the site says it recognizes more than 98% of spam mails. Additional Spam Word, Link, DCC, and Rule filters are built in, and users can add custom words and regular expressions. It works with clients supporting POP3 or IMAP, including Outlook and Mozilla Thunderbird, and uses SSL/TLS when the mail server supports secure connections. Recognized messages go to a Recycle Bin, where they can be restored; users can train the filter using spam and non-spam messages. An option deletes messages from blocked senders directly on the mail server without downloading them. Plugins can add recognition or features, though not all work with the 64-bit version. The download page lists version 1.7, dated June 5, 2022, in 32-bit and 64-bit versions and portable builds. English and German are included, and a language pack adds over 30 more languages. Online documentation and a support area are available, but support is not offered by email or telephone.
