I've got a vps running windows server 2008 r2 and I can setup websites on it but I need email support as I want to transfer all my sites across to this vps and they have their own mail server setup with their hosts but unfortunatley I'm unable to get my email sorted with this host, the mx points to my domain and then I have a cname pointing to my domain (cname being mail.domain.com) and then within my vps I have set the host to mail.domain.com, is this right?
