The Apps vhost looks dead to me for approximately 3 years and is thus probably disabled on lots of installations. However the Rspamd url is pointing by default on the Apps vhost. Shouldn't we add the Rspamd vhost to teh default ISPConfig vhost instead?
The exact opposite is the case. phpmyadmin, RoundCube, and Rspamd are configured to use the the apps vhost. Then, these users made a mistake by disabling it manually or they do neither need RoundCube, PHPMyadmin, Rspamd or any future app that gets integrated with ISPConfig. No other app besides ispconfig GUI should be accessed through ISPConfig vhost. Any other app must use apps vhost only.
Thanks for the quick answer Till. Maybe they configured phpMyAdmin and RoundCube to be available on all sites. Using the Apps vhost needs another port with all associated (dis-)advantages. But I understand your configuration idea and will adapt my personal setup by using a custom config file.
phpMyAdmin: Alias /phpmyadmin /usr/share/phpmyadmin RoundCube: Alias /webmail /var/lib/roundcube isn't that for all vhost?
The default setup for all URL's to access phpmyadmin and RoundCube is port 8081 for quite some time, but we add the other aliases still for compatibility reasons.
But my plan for the apps vhost, in general, is that we make port and domain name configurable in the future so that one can use a domain name on port 443 as well for it.
