Step 4: Adding protected domains
Step 4 of the Quick Start Wizard configures the protected domains.
Protected domains define connections and email messages for which the FortiMail unit
can performs protective email processing by describing both:
• the IP address of an SMTP server
• the domain name portion (the portion which follows the “@” symbol) of recipient email
addresses in the envelope
both of which the FortiMail unit compares to connections and email messages when
looking for traffic that involves the protected domain.
For example, if you wanted to scan email fro email addresses such as
user.one@example.com that are hosted on the SMTP server 10.10.10.10, you would
configure a protected domain of example.com whose SMTP server is 10.10.10.10.
You usually must configure at least one protected domain. FortiMail units can be
configured to protect one or more email domains that are hosted on one or more email
servers.
Exceptions include if you will not apply recipient-based policies or authentication profiles,
such as in “Example 3: FortiMail unit for an ISP or carrier” on page 128.

SMTP over SSL/TLS Enable to allow SSL- and TLS-secured connections from
servers and clients requesting SSL/TLS.
When disabled, SMTP connections with the FortiMail
unit’s SMTP server will occur as clear text, unencrypted.
This option must be enabled to use SMTPS.
SMTPS Server Port
Number
Enter the port number on which the FortiMail unit’s SMTP
server listens for secure SMTP connections. The default
port number is 465.
