GUI item | Description |
Allow different SMTP sender identity for authenticated user | Enable to allow the SMTP client to send email using a different sender email address (MAIL FROM:) than the user name that they used to authenticate. Disable to require that the sender email address in the SMTP envelope match the authenticated user name. |
Enable PKI authentication for web mail access | Enable if you want to allow web mail users to log in by presenting a certificate rather than a user name and password. Also configure “Certificate validation is mandatory”. For more information on configuring PKI users and what defines a valid certificate, see “Configuring PKI authentication”. |
Certificate validation is mandatory | If the email user’s web browser does not provide a valid personal certificate, the FortiMail unit will fall back to standard user name and password-style authentication. To require valid certificates only and disallow password-style fallback, enable this option. |
