Can someone please provide the checklist for my issue?

Hi everyone,

I have the exact same problem as described here :

I want this user:

user@separatedomain.com

To receive and send emails via mailinabox.

Currently this user can only send and not receive emails from outside the mailinabox domain name.

Can someone please provide the checklist of steps to make this happen ?

First, Check if separatedomain.com has mx record pointing to your box

Thanks! It didn’t - when I set the MX record with the domain company, it worked!
