The Sunisle Spam Firewall is a hosted email gateway appliance incorporating a comprehensive Spam and Virus filtering solution that ensures all email arriving at your mail server and network is Spam and Virus free.

The email Firewall system provides an integrated Anti-Spam and Anti-Virus solution offering complete email protection at the network perimeter level, before unwanted or potentially dangerous and costly email reaches your network or mail server.

The design of the email Firewall system leverages open source Anti-Spam and Anti-Virus solutions in conjunction with a number of additional filtering and defense layers to detect and filter out Spam and other unwanted email messages along with Viruses and other potentially dangerous attachments.

Filtering and defense layers and methods employed include Connection Control and Validation, IP/Domain RBL Blocking, Virus scanning with archive decompression, Spam Fingerprint Checking, and a comprehensive rule-based Spam Scoring System incorporating Content Analysis (Heuristics) and Bayesian Analysis.

This multi-layer Spam and Virus Filtering Technology results in a highly accurate Spam and Virus detection rate without filtering legitimate email.
