Caretaker Antispam combines a number of methods to distinguish spam messages from genuine messages. Each message receives a score by looking at certain features, for example the sender, contents, the make-up, etc.
Caretaker Antispam works differently from other antispam filters. Most filters need to be "trained" by the user to learn what is spam and what is a genuine message. Spammers know this, and have a number of tricks to mislead the filters. See the section below on tricks for more information.
Caretaker Antispam's filter is trained centrally, not by the user so when spammers find a new spamming method, the filter is updated automatically by the team of SurfRight experts.
This mechanism ensures that Caretaker Antispam continuously filters out more than 99% of all spam messages, while the number of false positives (genuine messages that are classified as spam) is virtually zero.
Main features:
-Finds more spam than other built-in and external spam filters.
-The multi-layer scoresystem of Caretaker Antispam evaluates every incoming e-mail message based on heuristics, statistical models, and innovative image analysis.
-Analyses phrases - instead of single words - and thus identifies more spam than traditional text filters (Bayesian filters).
-Identifies all image based spam, despite diffuse patterns, font size and colours.
-NEW Smart link analysis automatically detects spammy web pages on hacked legitimate websites, advertised in spam messages.
-For up-to-the-minute detection Caretaker Antispam analyzes the distribution of spam versus legitimate email for the message recipients and calculates a receiver reputation for each based upon that distribution.
-Identifies URL spam, Phishing emails, stitched images, Invisible ink, PDF spam, Excel spam, etc.
-Detects potentially dangerous files by checking the contents of attachments.
