Symptoms

On cPanel/WHM v132 the 'SSL Minimum Protocol' version you switch to does not change after saving.

Description

This does not appear to be just a visual issue, as the value within "/etc/dovecot/ssl.conf" is not updated.

Workaround

An update has been released regarding CPANEL-50271 as part of cPanel v132.0.11. Once your server is updated to this version, changes to the SSL Minimum Protocol version will be properly saved. If you are unable to update, the following workaround can be used instead:

  1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.

  2. Run the following command.

    sed -i 's/ssl_min_protocol = SSLv3/ssl_min_protocol = TLSv1.2/' /etc/dovecot/ssl.conf

  3. Restart Dovecot.
