Cloud Antispam
 
Š˛UserGate Mail Server interfaces with the Cloud Antispam online service via HTTP POST requests. Each request to the online server contains a unique message hash computed based on the full message body (including headers). Hash does not contain any information about email content and cannot be used in any way to disclosure any confidential information. A reply from service containing a notification with options as follows: Spam / Not spam / Suspicious / Error, and a decision to block the message is made on the applicable option.
 
Note that Cloud Antispam offers the best filtering of unwanted mail (minimum 97% efficient), at the same time keeping a low threshold of false spam detection (maximum 1 out of 1,500,000 messages).
