Our CentralNic Reseller Mailspaces provide the possibility to allocate a certain amount of data storage exclusively usable for Mailboxes. The Mailspaces can be used very flexible. For example, you can allocate a certain amount of data storage - a Mailspace, and add Mailboxes to your liking to this Mailspace. The allocated storage for Mailspaces can be altered, also Mailspaces and Mailboxes can be disabled, activated and deleted. Furthermore Mail Forwarding can be set up. Mailspaces are billed in monthly terms, regardless of the number of Mailboxes within a Mailspace.

Recommended Workflow

  • Prior to setting up Mailboxes a Mailspace needs to be created.
  • Afterwards Mailboxes can be added to this Mailspace.
  • As long as Mailboxes exist within a Mailspace, Mail Forwardings can be set up.

How it works

The MX record of a domain which should use an CentralNic Reseller Mailspace needs to point to the Mailspace IP address. The respone of a StatusMailspace command contains the IP address of the Mailspace, for example:
