Domain pointed to server

[GhoumaTn]

Hi,

I have littel problem here, I have domaine exemple.com, I point *.exemple.com to my server ip 111.222.333.444
so whatever i put in "*" for exemple : test.exemple.com website get last domain saved on vestacp.

if i add exemple2.org then test.exemple.com will render exemple2.org.
how can i fix this.

PS : I like to keep *.exemple.com in DNS management.
