My VPS came with a default domain (lets say http://vpsname.com), which was very random long domain name. This VPS hosts two websites, lets call them websiteA.co.uk and websiteB.co.uk.
At the moment mail gets sent from vpsname.com, even if I use an authenticated email system emails get classified as Spam since they don't come from the matching domain name.
The server runs Virtuozzo, Plesk, Parallels etc, and an Apache PHP server.
I want to change http://vpsname.com to vps.websiteA.co.uk
Do I just superuser and change the hostname, or is it more complicated than that?
I access the VPS by IP, so I am not worried about URL access as such, I just need email to be sent from websiteA.co.uk
Can anybody provide me with any advice, I am new to VPS's...
Thanks a lot
