Configuring the session profiles

Follow the steps below to create two session profiles for connections: one profile for external (example shown below), and another profile for internal SMTP clients.

For more detailed information about session profile configuration settings, see the FortiMail Administration Guide.

1. Go to Profile > Session > Session and click New.
2. Enter a Profile name.
3. Under Connection Settings, enable Hide this box from the mail server to preserve the IP address or domain name of the SMTP client.
4. Under Sender Reputation, click Enable sender reputation and leave the settings to their default values.



5. Under Session Settings, enable Prevent encryption of the session so that STARTTLS/MD5 commands are blocked and email connections cannot be TLS-encrypted.
6. Under Unauthenticated Session Settings, enable Prevent open relaying.
7. Click Create.
