Antispam Overview

IMail standard edition includes standard antispam technology; IMail Premium includes Premium Antispam as well as Standard Antispam technology.

Premium Antispam

Commtouch Advanced Security Daemon (a.k.a. ctasd™) 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.

Commtouch's GlobalView™ Mail Reputation Service fights unwanted mail at the perimeter, reducing more than 85% of incoming messages at the entry-point, before these messages enter the network. Additionally, GlobalView can optimize traffic flow so that legitimate sources gain optimal access, while unauthorized sources attempting to abuse the network are blocked.

Standard Antispam

All IMail products include standard antispam features. These 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.

What You Can Do with the Antispam Features

Which Antispam Settings are Used to Check a Message?

The antispam filters used to scan a message are determined by the IMail domain settings of the IP address that the message is received on.  If the message is received on an IP address that is not configured for IMail, the primary domain's antispam filter settings are used.

Spam Actions

If a message is identified as spam, you can set IMail Server to delete it, send it to an e-mail address, or insert an X-header in the message to identify which spam test it failed. You can also create delivery rules to search for the spam X-Headers and process the message accordingly.

Accessing the Antispam Features

The Antispam options are accessed from two levels: the server level and domain level.
