My domain name and Email is hosted by 1and1. I have recently developed a new site & blog with WP with my 1and1 domain name which compliment's my business well - really chuffed. However my Email has stopped working with 1and1. To get my email working again 1and1 have told me to point my MX records back to 1and1.
Have have tried this under the Domains/Custom DNS section of my dashboard by am neither sure if that is the right place, and it doesn't understand the format I have written even if it is.
