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.
