I'm taking over ownership of a domain that points to an exchange server. I've not setup a domain that's been used for this before. Normally I just point the nameservers to an NS address of my VPS and my VPS handles it all for me.
This domain needs to relay email to the exchange server and also allow the website to be accessed and hosted by my VPS.
Can someone please explain me how, using 123-reg, I can setup the domain to do all this when it's transferred to me?
