Based on the structure and headers of e-mail messages several analysis are performed.
> Heuristic / Bayesian
By recognition of character and word combinations, message content can be classified.

To recognize known spam senders and messages several leading white and blacklists are used.
Heuristic Image Character Recognization: allows detection of characters and words to classify images.
> Mail Server Protection

> Attachment Type Control
You control which types of attachments are allowed or blocked.
