anti-spam

Syntax

Hierarchy Level

Description

Configure UTM antispam features. You can also configure the default UTM configuration for antispam feature profile. If you do not configure any option in the antispam feature profile, the values configured in the default UTM configuration are applied.

The antispam feature examines transmitted e-mail messages to identify e-mail spam. When the device detects a message deemed to be spam, it blocks the e-mail message or tags the e-mail message header or subject with a preprogrammed string. Antispam filtering uses both a third-party server-based Spam Block List (SBL) and optionally created local allowlists (benign) and blocklists (malicious) for filtering against e-mail messages.

Note:

A license check for the antispam configuration is performed at the time of a commit and will provide a warning if a valid license is not installed on the device. Once a valid license is installed on the device then a custom antispam profile or the default profile will be able to process traffic. If a license is expired or is not installed, the antivirus service will not process traffic.

In the default UTM profile, the antispam type is configured as SBL instead of none. This configuration enables SBL. However, to use this feature, you must enable the SBL server using the [edit security utm default-configuration anti-spam sbl sbl-default-server] command.
