About IMail Anti-spam
IMail Premium includes Premium Anti-spam technology by Commtouch.
- Commtouch Advanced Security Daemon (a.k.a. ctasd™) is a plug-and-play email-borne spam and malware outbreak detection daemon that combines your current core messaging network infrastructure with advanced detection and classification capabilities. The daemon adds a layer of e-mail filtering to your mail delivery system in order to provide real-time classification, already in the first minutes after a new outbreak is launched.
- The Commtouch GlobalView Mail Reputation daemon (ctIPd™) is an embedded reputation engine with a small footprint. It is responsible for maintaining communication with the Commtouch Datacenter. ctIPd delivers reputation data to messaging, security and networking devices, providing an added layer of protection while saving valuable resources by enabling the messaging network to analyze and process requests before message reach the network. These querying devices post queries to ctIPd over HTTP, UDP, or RBL/RBL+ protocol requesting reputation data on source IP addresses attempting to establish SMTP sessions for sending messages to recipients.
All members of the IMail product family also include standard anti-spam features. The anti-spam features are custom configured by the administrator to identify spam and prevent it from clogging your inbox. Mail messages are passed through several layers of filters and tests to assure that maximum spam detection is achieved.
The Premium Spam Filter performance can be improved when users forward spam e-mail to Commtouch. Commtouchs' editors review the spam submission and add spam signature information to it; then the signature is published to the global database to help other users eliminate spam.
After installing you can access the Anti-spam settings by clicking the Anti-spam tab in IMail Administrator. The Domain Level Spam Filter page appears.
To access the Premium Anti-spam settings (available only with IMail Premium), click the Premium Filter link.
To access Premium Anti-spam Service settings go to Services > Anti-spam.
