ENTERPRISE DESKTOP SOFTWARE
Accurately Catch Spam
For each message, Mailshell Anti-Spam applies
checks of its four spam detection engines:
• SpamBulk Engine: Is the message or similar
messages sent in bulk?
• SpamRepute Engine: Do most people want the message?
• SpamContent Engine: Will most people consider
the message offensive?
• SpamTricks Engine: Is the message formatted or
sent to bypass anti-spam rules or to be economical
For every message, the four engines check over a
thousand rules and several locally cached databases.
Mailshell Anti-Spam also creates a fingerprint ID for
every e-mail message and compares it to existing
fingerprints in its databases. Customers can opt to
receive scheduled or real-time rules updates. The
results of all of the engines are combined using
SpamScore, a proprietary Bayesian statistical
formula, into one final spam probability score.
Since spam constantly evolves, the Mailshell
SpamLabs continuously collects and analyzes millions
of new spam and legitimate messages and user
feedback to tune the rules and databases and adjust
the weighting of existing rules.
