Once you have activated Mail Forwarding you will need to make sure you set your MX records. If your domain or host is not managed by No-IP.com, you will need to specify our mail server for your domain. This is done by setting your first priority MX record to mx.noip.com. If you purchased Mail Forwarding for a No-IP Plus Managed DNS domain or a No-IP Free Dynamic DNS hostname, the MX record will be added automatically.
You can create a forward account when you login and go to “Mail”, then “Configure”, next to “Mail Forwarding”. You can now select “Add New Account” and create the forward user and the forward to addresses, then click “Add Forward”.
