How do I secure Plesk mail with SSL?

When you send and receive email via your domain name using IMAP, POP, and SMTP, you should secure the mail with an SSL/TLS certificate. This provides increased security to your mail, allowing you to use secured ports during setup and enhancing your trustworthiness; it is also more professional.

You can easily secure your mail in Plesk for free! The built-in Let’s Encrypt tool makes this straightforward, direct from your Plesk control panel. Unsure how to access Plesk? Learn how to access your control panel here.
