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 unwanted sender address patterns,

•filtering 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:

1Select email filter options in a new or existing content profile. See “Adding content profiles” on page 167.

2Select 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 content profiles to policies” on page 169.

3Add 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 250.
