/webmail global alias should be redirect
The /webmail global alias requires a shared roundcube installation which is insecure.
Solutions would be:
- have /webmail redirect to the roundcube install at the server's hostname
- setup reverse proxy for /webmail to the roundcube install at the server's hostname
- configure a dedicated php daemon for phpmyadmin that all sites use for the /webmail path but is not available as an alternate php version
