- Extensive Mail Control
- Personalized filter training
-
- Spam Terriers Bayesian filter, the core of the program, can be trained to recognize new spam when it arrives. Because spam is different for different people, you get to define what should be considered spam by telling Spam Terrier what, from your past email, you consider to be spam. The filter then learns certain behavior/appearance patterns and applies these characteristics to spam filtering of future messages.
- The Bayesian filter is based on probability algorithms that assess the odds of new messages having the same characteristics as past emails designated as spam. The more thoroughly you train Spam Terrier, the more accurate and tailored to your requirements the results will be.
- Adjustable sensitivity thresholds
-
- Each incoming message is assigned a "spam score" by Spam Terrier, which classifies the message as not spam/probable spam/definite spam. You can change the way these calculations are made by modifying the values the scores fall into to suit your level of tolerance.
- Definable whitelists and blacklists
-
- Spam Terrier doesnt limit its filters to the use of senders white- or blacklists (respectively, the list of allowed/blocked senders) when it processes emails. Users can also create special filters based on a number of variables: for example, message body text, header content, or email subject. Email addresses in users address books are automatically added to the list of legitimate senders.
- No lost messages
-
- Suspected spam messages are put into a special folder that you can check at your convenience and restore any misclassified messages. You can also expand the Spam Terrier Bayesian database by clicking "mark as not spam" on any valid message in the Spam folder.
- View message status
-
- By clicking on any message in any folder, users can see how likely that message will be flagged as spam by reviewing its cumulative spam score. Users also thus get valuable insight into how the ranking works in practice.
- Continuity of Protection
- Automated spam check
-
- Spam Terriers real-time self-learning algorithm ensures every incoming message is automatically analyzed against the programs indicators to determine the legitimacy of the message. Suspicious emails are then quarantined for later review.
- As Spam Terrier constantly scans new mail in search of fresh spam samples on which to base its junk mail database updates, the accuracy rate increases over time and minimizes the number of false positives while maximizing the spam identification rate.
- On-demand scan
-
- Spam Terrier can check existing email folders for the presence of spam. This on-demand spam scan removes junk emails in advance from any specified folders, and ensures that mailboxes start out as clean as possible.

ASEMCA: Anti-Spam E-Mail Checker and Autoresponder is a colourful, stand-alone, talking e-mail checker more>>
It displays messages in user-defined text and background colours and can be installed and run on a computer without administrative privilege. It is a rules processor, Bayesian filter, auto-responder, e-mail checker, colour-coder and e-mail reader all at the same time.
ASEMCA operates on the following logic or philosophy: (a) If you are sure it is junk mail, delete it; (b) If you are sure it is good mail (i.e. not junk mail), accept it; (c) If you are (sure you are) not sure it is good mail or junk mail, reject it (i.e bounce, challenge or, preferably, auto-reply to it).
ASEMCA assumes that junk mail or "spam" evolves in many ways and originates from many places including virus-infected computers of friends. Thus, the best way of detecting and reducing the junk mail we receive is to use a variety of techniques including (a) a smart or Bayesian filter, (b) a list of allowed terms or passwords, (c) a list of disallowed terms or junk mail characteristics, and (d) an autoresponder for ambiguous or difficult-to-characterize mail.
ASEMCA can be used as a colourful e-mail checker, a Bayesian or statistical anti-spam filter, a simplified challenge-response e-mail program, an auto-responder and e-mail processor, or a flexible rules-based anti-spam filter. Its strength lies in combining all or some of these features.
