I run a synology server and i direct my dos through to the server which works fine, what do i define my mx record as ?

My emails work across the lan but don't get routed through the mx record as i haven't defined it properly

Thanks

Simon

If you have 'Wildcard Alias' enabled, then all the subdomains point to the same primary domain name. So you can just use any hostname as your MX record to receive the emails. You can go into the MX records area in the control panel and leave the node field empty and put 'mail.testfocusinternational.com ' as the MX record as you have done correctly.
