Hi,

I have been trying to set up email hosting for my domain benporter.co.uk with your service

here is a screens shot of the DNS records I have setup:

I am able to send out emails from ben@benporter.co.uk

but when I send email to this address from an exterior address to the above address I get 'undeliverable' back with the following error message:

mx.zohomail.com gave this error:
Remote server returned an error -> 553 Relaying disallowed
