Spam filter

Spam filter provides configuration access to the spam filtering options you enable
when you create a firewall protection profile. While spam filters are configured for
system-wide use, you can enable the filters on a per profile basis. Spam filter can be
configured to manage unsolicited commercial email by detecting spam email
messages and identifying spam transmissions from known or suspected spam
servers.

Table 34

describes the spam filter settings and where to configure and access them.

To access protection profile spam filter options go to Firewall > Protection Profile, edit
or Create New, Spam Filtering. See

“Protection profile options” on page 222

.

Table 34: Spam Filter and Protection Profile spam filtering configuration

Protection Profile spam filtering options

Spam filter setting

IP address BWL check

Spam Filter > IP Address

Black/white list check. Enable or disable

checking incoming IP addresses against the

configured spam filter IP address list. (SMTP

only.)

Add to and edit IP addresses to the list. You

can configure the action to take as spam,

clear, or reject for each IP address. You can

place an IP address anywhere in the list. The

filter checks each IP address in sequence.

(SMTP only.)

RBL & ORDBL check

Spam Filter > RBL & ORDBL

Enable or disable checking SMTP traffic

against configured Real-time Blackhole List

and Open Relay Database List servers.

Add to and edit RBL and ORDBL servers to

the list. You can configure the action to take

as spam or reject for email identified as spam

from each server. (SMTP only.)

IP address FortiShield check
Enable or disable Fortinet’s antispam IP

address black list: FortiShield. This service

works like an RBL server and is continuously

updated to block spam sources. See

“FortiShield IP address black list and spam

filter” on page 337

.

HELO DNS lookup
Enable or disable checking the source domain

name against the registered IP address in the

Domain Name Server. If the source domain

name does not match the IP address the

email is marked as spam and the action

selected in the protection profile is taken.
