Overview

This support article describes how to secure Webmail URL with a Let’s Encrypt Free SSL Certificate.  When accessing your Webmail from an untrusted or unsecured network (eg from a free WiFi service), an SSL certificate will ensure that your email username and password (as well as the email itself) is encrypted and therefore can’t be viewed by others.
