How Commtouch Operates to Maintain a Spam-free Environment:


	Inbound email enters the Commtouch Enterprise Gateway, a software add-on to the enterprise SMTP server.

	The Commtouch Enterprise Gateway matches key characteristics of the message with predefined spam policies created by IT managers or end-users.

	If the Gateway does not match the message to a known source, either spam or not spam, it compares characteristics of the incoming message against the Commtouch Gateway database of recently identified spam.

	If the message remains suspicious, but cannot be confirmed as spam, the Commtouch Gateway queries the Commtouch Service Center for remote spam detection and classification services.

	The outgoing query consists of encrypted digital signatures taken from e-mail header information to ensure the enterprise security and confidentiality.

	The Commtouch Service Center weighs the values of the outstanding query against its vast database of real-time information about known spam messages and sources of spam, and replies to the Commtouch Enterprise Gateway with a unique and up-to-date classification.

	The Commtouch Enterprise Gateway applies a locally predefined action to the message and may store the information internally to match against new incoming messages bearing similar characteristics.
