Demon Relay Change

On 29 May 2013, we’ll be making some changes to our email service, which will affect customers who use our email relay MX service and manage their own service configuration within their network.   We’re aware that some customers use IP addresses instead of server names in their service configuration. From 29 May, the network IP range for this service will be changing.

To avoid problems with email delivery, please configure your service to accept network connections from the server names ( and and NOT the IP address.
