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.
- Log in to Plesk or Conetix Control Panel.
- Click on Website & Domains > Let’s Encrypt:
- Select the checkbox Secure webmail on this domain

To confirm click on Website & Domains > SSL/TLS Certificates and you should see the below.

- To access Emails for email@example.com the URL will be https://webmail.conetixtest.com .
