need placeholders for Webmail (and PHPMyAdmin) URL
For proper configuration of (some) multiple server setups there needs to be some more placeholders in the Webmail URL particularly. I will have multiple web servers separate from email servers, and there is no way to set the Webmail URL to a website's own server.
Eg. in PHPMyAdmin I use https://[SERVERNAME]/phpmyadmin and it redirects to the webserver's hostname and works. But I enter https://[SERVERNAME]/webmail for the Webmail URL and it redirects to the mail server's hostname and fails (as there's no web server there).
I need a placeholder for either the webserver of a domain or at least the domain name itself. Maybe preserve existing behavior for SERVERNAME, then add a DOMAIN placeholder (current domain for PHPMyAdmin, or right-hand side of email address for Webmail), and if possible also a WEBSERVER, MAILSERVER and DATABASESERVER?
