Issue Unable to create Let's Encrypt certificate for "webmail." sub-domain

Jens Reimann

New Pleskian
Although it is possible now with Plesk to assign a certificate to the "webmail." sub-domain, the Let's encrypt extension does not add the alias to the certificate request.

This will result in the "webmail.domain.my" sub-domain to be served with a certificate of only "domain.my" and "www.domain.my". Which results in a certificate error in the browser and if you have HSTS activate for your domain event prevents you from accessing the webmail at all.
