the console show me my ip adress, when i type cat /etc/mailname
it shows me my-ip-adress.internetserviceteam.com
I have no idea if it's a problem or not, but i was lokking through a lot of postfix install tutorials, and there when typing cat /etc/hostname they were geting their site name. Why do i get just a ip-adress? Maybe i messed up something when i set up my dns and domains with the webmin tool (I did that for the first time in my life)?
