I have MXroute up and running great for my domain (example.com). DNS configuration is fine and mail works for the 4-5 accounts I’ve created for the domain.
I’m interested in creating a mail account for a subdomain of my domain (app.example.com). Is this possible? I’ve explored adding it as a subdomain in the administrative interface, but it’s not clear if I need to alter/add DNS records to Cloudflare or make any other changes in order to begin creating working mail accounts.
