VisNetic MailPermit: Spam Email Blocker Functions

• Blacklists

This spam email blocker will automatically block any email from a known, blacklisted email address. VisNetic MailPermit features blacklists at the system, domain and user levels--putting this spam email blocker in the hands of all your users.


• Email Scoring

VisNetic MailPermit uses rules-based anti-spam tools and Bayesian email content filtering to individually score email messages. The ability to define score thresholds and opt to delete a message based on its score serves as a powerful spam email blocker feature.


• Challenge-Response System

Challenge-response anti-spam technology shifts the burden of effort from email recipients to email senders, by requiring them to obtain authorization to deliver their email message. If they do not complete the authorization requirement, their email messages are blocked and never appear in your mailbox.
