I will try to do it.

Setting up certificate for a hostname: mactt.hkpower.com

[root@mactt ~]# hostname

Where I can change the hostname to mactt.hkpower.com (within directadmin?)

In admin section under "Administrator settings" -> extra features".
https://yourdomain.com:2222/CMD_ADMIN_SETTINGS

But there is more too it. I would suggest creating a seperate entry for the hostname too. As admin.
 
I suggest use this command.
if on Rhel( include all forks OS ), Debian( Ubuntu )
Code:
hostnamectl set-hostname host.domain.com

it better than just
"hostname host.domain.com"

and then change in Administrator settings.


after in all that . Rebuild exim_conf
Code:
da build exim_conf
