[hazim]

Description	This article describes how to configure SMTP using a custom server and port on FortiGate.
Scope	FortiGate.
Solution	From GUI: Check the current SMTP server and port configured in the FortiGate. Go to System -> Settings and select Email Service. Choose to use 'Custom Settings' and specify the server domain name and custom port as per the example below:  Select the Apply button to save the configuration. From CLI: config system email-server     set type custom     set server "test.com"     set port 555 end To test the configuration, use the following command to generate a test email: diagnose log alertmail test This configuration sends an alert email, email FortiToken code, and local reports (for the FortiGate model with disk). Starting with v7.4.4, the default email server has changed from notification.fortinet.net to fortinet-notifications.com. This server is only available for devices registered with an active FortiCare support contract. The reply-to field in the source email is now automatically updated to DoNotReply@fortinet-notifications.com for all servers, including custom ones. For some custom SMTP servers, the reply-to field will be checked. If the custom SMTP server requires this field, the option is to upgrade to a higher version than v7.4.4, as this option is not available in v7.4.4. If the debug shows email sent successfully, but the email is never received on the recipient's end, check the reply-to field and the SMTP server requirements on this.
