I don't have an actual issue, however I do have something I would really like to do.
Using the email address example name@domain.com I can send mail from that email address and receive mail towards it - but only mail sent from another account within the server. What does work, however, is name@mail.domain.com. I set up iRedMail using mail.domain.com except for when it asked for my first virtual domain name, to which I put domain.com. I can send emails from outside of the mail server when I use mail.domain.com, however when I try to send an email to name@domain.com I get an error message the Hotmail postmaster account. In setup I wasn't allowed to use domain.com for all fields, as the virtual domain name had to be different, otherwise I would have done so and just hosted my website on the same server.

Can someone enlighten me on either what I am misconceiving or what I need to do to achieve what I want? As a summarising example, I want to be able to send and receive mail whilst having the email address name@hotmail.com, not name@mail.hotmail.com.
