Hi to all,

I have a customer who has a new cPanel account created on my server and he would like to use his existing icloud email with his domain name (mydomain.com).

My question is do I achieve this by simply creating a forwarding rule?
In which case he would need an email account linked to his domain name (i.e. [email protected]) which will be forwarded to his icloud email address.

What about using MX Records with Remote Mail Exchanger?
How does this work and why would I use this method?

What is the difference between both options above?
