SpamHalter is a daemon for the Mercury/32 server that provides centralised SPAM protection for all local e-mail accounts.

Previous versions are called as SpamWall. From version 4.3 we are renamed this program to SpamHalter.

SpamHalter major features:

  • Integrated Bayesian filter - no external server needed.
  • Adaptable - The Bayesian filter is a learning filter. You can teach the filter what is SPAM and what is not SPAM by simply forwarding a message to a local e-mail address eg: spam@yourdomain.dom, notspam@yourdomain.dom
  • Native WIN32 code - external script interpreters like PERL is not needed.
  • Robust - designed for high traffic business servers hosting many accounts.
  • Fast - SQLite3 database backend serves as a common database for all accounts.
  • Around the clock protection - SpamHalter runs 24×7 mode and there is stopping the daemon/database for recalculations.
  • Accurate - detects more then 99% of SPAM. Probability of badly marked message as SPAM is only 0.01%! This is equal to, or better than, many expensive commercial products.
  • Affordable - SpamHalter is free for personal and commercial use.

Because this product is free, we cannot guarantee any technical support! Your questions to address may not be replied. However we are anxious to please all donation senders.

Even if this program is free, it cost lot of author's time and effort. We declare this software as donationware. Please, send any donation by PayPal, by MoneyBookers, or by your CreditCard. Thank you very much! Unofficial SpamWall/Spamhalter WIKI pages
