Host Name & IP

Host Name & IP

Disable this domain (Cloud only)

Click this checkbox if you wish to disable the domain. Disabled domains are treated by MDaemon as if they do not exist. Domain users will not be able to send or receive mail and MDaemon will not accept incoming mail for the domain. This option is only available in MDaemon Private Cloud.

 

SMTP host name

This value is the Fully Qualified Domain Name (FQDN) that will be used in the SMTP HELO/EHLO instruction when sending mail for this domain. For incoming connections, if the This domain recognizes only connections made to the host IP address option below is used, the domain is bound to its own IP address and the proper FQDN will be used for connections made to that domain. Using that option, however, is not strictly required for this to work. But, if you have two or more domains using the same unbound IP address then the FQDN used will be the one that is associated with the domain that is first in alphabetical order.

In most cases the FQDN will be either the Domain name or a subdomain of it (for example, “mail.example.com”), but an IP literal syntax such as “[192.0.2.0]” may also be used. When no FQDN value is specified, MDaemon will use the Default Domain’s FQDN.

IPv4/IPv6 address

Enter the IPv4 and IPv6 addresses to associate with this domain. If an IP address is missing MDaemon will automatically try to detect a suitable address for use.

Detect

Use these buttons to detect the IPv4 and IPv6 IP addresses that are eligible for use in the corresponding IP address options. You can then choose from the IP addresses listed.

This domain recognizes only connections made to these IPs

Click this checkbox if you wish to restrict this domain's incoming connections to the IP addresses specified above. By default this only applies to inbound connections. Outbound socket binding is governed by an option under "Server Settings » Binding."
