Incoming Mail ■ Accept TLS — Enable this option to accept SSL/TLS for incoming mail
connections.

“SMTP
Authenticated Relay” section on page 40 for more detailed
information.
Mail Delivery By Default
■ Offer TLS — Enable this option to offer remote mail servers the option
of using SSL/TLS when sending mail.
■ Enforce TLS — Enabling this option will require the validation of a
CA-signed certificate when delivering mail to a remote mail server.
Failure to do so will result in mail delivery failure.
