Using Custom Vhost Entries for Webmail, MySQL, Etc.

[karlis]

Code:

Alias /webmail /etc/sentora/panel/etc/apps/webmail/

as a Global Vhost Entry in Module Admin > Apache Config.
This allows all domains and subdomains to use domain.com/webmail to access roundcube and has worked without flaw for a few years now.
(I also use a similar variation for external phpmyadmin login.)
Doing it this way also prevents clients from having to add a webmail record to their DNS settings. Much easier for everybody

Tried it and it gives me a blank page. Any idea why?
