For the technically minded out there it's now been virtualized on VMware Vsphere Esxi server and I've split my mail server on to another virtual machine on the same ESX server along with a server 2012 VM which is doing DHCP and DNS for me.
So I've put three operating systems on to one server which will save on my power bill.
The fans in the old server were getting very noisy and were starting to give me the shits so that was another reason.
While I was at it I pensioned off the imac and gave it to the missus because that was giving me the shits as well

If you didn't understand a word of what I just said don't worry. It confuses the hell out of me too and I teach it
