DNS things, as usually

[kilburn]

First of all, notice that there's another file "db_e.tpl", that is used for "normal" domains (db_master_e.tpl is only for the master/panel domain).

"apache2ctl -S" should give you a hint about which namevirtualservers are configured and in which order (if the request doesn't match with any serveralias/servername, then it is handled by the first virtualhost in that IP).

Paste the output here if you can't figure it out by yourself
