Messaging

FortiAuthenticator sends email for several purposes, such as password reset requests, new user approvals, user self-registration, and two-factor authentication.

By default, FortiAuthenticator uses its built-in Simple Mail Transfer Protocol (SMTP) server. This is provided for convenience, but is not necessarily optimal for production environments. Fortinet recommends that you configure the unit to use a reliable external mail relay.

There are two distinct email services:

1. Administrators: Password reset, new user approval, two-factor authentication, etc.
2. Users: Password reset, self-registration, two-factor authentication, etc.

If you plan to send SMS messages to users, you must configure the SMS gateways that you will use. Ask your SMS provider for information about using its gateway. The FortiAuthenticator SMS gateway configuration differs according to the protocol your SMS provider uses.
