Sub-domains...where is the folder?

when i create one subdomain (webamail.domain.tdl) in ISPconfig it doesent create any special folders...and when i write webmail.domain.tdl into my browser i get the default domain.tdl page. And ISP also adds an alias (in Vhosts_ispconfig.conf) to domain.tdl ->

Code:

######################################
# Vhost: www.domain.tdl:80
######################################

and I cant find the folder of this subdomain... HELP!!!

 

If you create a sub-domain (co-domain) you actualy only create an alias.

To create a 'true' sub-domain you have to create a 'new' site and call it i.e. webmail.domain.tld. You can do that under the same user so that the admin is still in full control.
