SmarterMail SSL email settings

We support email encryption using TLS (Transport Layer Security) or SSL (Secured Socket Layer). To take advantage of this feature, you will need to configure your email client with the correct TLS/SSL settings.

There are two email settings you can choose to encrypt your connections between your email client and our mail server: TLS or SSL. We recommend using TLS (or "Auto," if available).
