A hostname, combination of optional subdomain and mandatory domain, may be configured to act as an e-mail domain, ie. receive e-mails on that host. These hostnames are added via Mail > Mail Routing. For any domain present there, the server will act as the final destination bypassing MX lookups. This will result in problems if you use third-party MX records.
The following is a brief list of composite examples:
|E-mail delivers to same inbox unless namespaced
Once a hostname is authorized through Mail Routing, corresponding DNS entries are created and will be active so long as you use our hosting nameservers.
Third-party nameserver DNS
If you use third-party nameservers – nameservers other than ours – use the following DNS template to properly route mail once a hostname is added in Mail Routing:
<hostname> IN MX 10 mail.<hostname> mail.<hostname> IN A <IP address>
