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 .

SMTPS Server Port
