Change hostname and domain of server

[dayjahone]

So, I did the perfect setup...on ubuntu feisty...everything is set up and working fine; however, I bought an ssl certificate which is different from the info I used to set up the server...which is fine because port 81 works regardless of which domain. The problem is /mailuser tends to want to go back to the server's hostname and domain and gives the self-signed certificate error. So, my question: is there a simple way to change the server's hostname and domain? And will it affect ispconfig and everything else? If not, is there a way to make it so mailuser doesn't keep trying to use the server's domain?

Thanks.

Please chnage the hostname in:

/root/ispconfig/httpd/conf/httpd.conf
/home/admispconfig/ispconfig/lib/config.inc.php

in addition to changing it elsewhere? Or is these the only two places where I need to change it?

This are the only places that affect the ispconfig web interface.

It still tries to switch back. Where else should I change it? I changed it once in each of the files you posted.

Is the value of ServerName correct in /root/ispconfig/httpd/conf/httpd.conf?

System -> Administration -> Network
Select DNS tab and change the fully qualified hostname.
