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.

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.
