Email filter
Email filtering is enabled in firewall policies. When you enable Anti-Virus & Web filter
in a firewall policy, you select a content profile that controls how email filtering
behaves for email (IMAP and POP3) traffic. Content profiles control the following
types of protection to identify unwanted email:
• filtering of unwanted sender address patterns,
• filtering of unwanted content,
• exempting sender address patterns from blocking.
This chapter describes:
• General configuration steps
• Email banned word list
• Email block list
• Email exempt list
• Adding a subject tag
General configuration steps
Configuring email filtering involves the following general steps:
1 Select email filter options in a new or existing content profile. See “Adding a content
profile” on page 197 .
2 Select the Anti-Virus & Web filter option in firewall policies that allow IMAP and POP3
connections through the FortiGate unit. Select a content profile that provides the email
filtering options that you want to apply to a policy. See
“Adding a content profile to a
policy” on page 199 .
3 Add a subject tag to the unwanted email so that receivers can use their mail client
software to filter messages based on the tag. See
“Adding a subject tag” on page 280 .
Note: To receive email filter log messages, see “Configuring logging” in the Logging
Configuration and Reference Guide . For information about email filter log message categories
and formats, see “Log messages” in the FortiGate Logging Configuration and Reference Guide.
