web-based manager.
2 From Show Users Of Domain, select example.com.
3 Select Create New.

Configure the email clients of local and remote email users to use the FortiMail unit as
their outgoing mail server (SMTP)/MTA. For local email users, this is the private network
IP address of the FortiMail unit, 172.16.1.5; for remote email users, this is the virtual IP on
the FortiGate unit that maps to the FortiMail unit, 10.10.10.1 or fortimail.example.com.
If you do not configure the email clients to send email through the FortiMail unit, incoming
email can be scanned, but outgoing email cannot.
Also configure email clients to authenticate with the email user's user name and password
for outgoing mail. The user name is the email user's entire email address, including the
domain name portion, such as user1@example.com.
If you do not configure the email clients to authenticate, email destined for other email
users in the protected domain may be accepted, but email outgoing to unprotected
domains will be denied by the access control rule.
Basic configuration is now complete, and the installation may be tested. For testing
instructions, see "Testing the installation" on page
For information on configuring additional features, see the

separated from local email users' computers by a firewall. Remote email users' computers
and external email servers are located on the Internet, outside of the private network. The
FortiMail unit hosts and protects accounts for email addresses ending in
"@example.com".
