Hi.. I've created a user for email only (firstname.lastname@example.org) and this work with setting mail.domain.com.. Now I've created a sub-domains and I've applied to this an SSL certificates.. When I try to receive the emails by Outlook, I receive an error.. If I try to open the link mail.domain.com in my browser, they redirect me to subdomain1.domain.com.. Why? Is this the problem..?
