How to Setup Backup MX


The purpose of this guide is to provide you with general instructions for configuring Backup MX on your domain name.

If you are using No-IP as your domains Managed DNS provider, we will automatically update your MX records for you once Backup MX is purchased.

Note: We will not start holding mail until the MX records are set.

If you are not using No-IP as your Managed DNS provider, follow these steps to configure your Backup MX service:

  1. Login to the DNS provider of your domain and set the MX records to the following:
    1. Mail.yourdomain.com – priority 5
    2. Mail1.no-ip.com – priority 10
    3. Mail2.no-ip.com – priority 15

To confirm your domain is configured properly with No-IP, follow these steps:

  1. Login to your No-IP account
  2. Click “Hosts/Redirects” in the navigation
  3. Click “Modify” next to the domain you want to verify the configuration of Backup MX on
  4. Ensure the following MX records are listed
    1. Mail.yourdomain.com – priority 5
    2. Mail1.no-ip.com – priority 10
    3. Mail2.no-ip.com – priority 15

Example:

Host Priority
mail.yourdomain.com 5
mail1.no-ip.com 10
mail2.no-ip.com 15

Backup MX ensures that you won’t lose any emails that are received if your mail server experiences downtime.

If your mail server becomes unavailable, our mail server will accept and hold your emails. Once your mail server becomes available again, we will deliver your emails to your mail server.

Our servers will check to see if your server is up on a sliding interval starting at 5 minutes to 45 minutes, depending on how long your server is down.

Please ensure that your mail server is functioning properly before you put it back online. If your server is responsive but rejects a message we try to deliver, those messages will be returned as undeliverable (bounced) to the sender. No-IP does not keep
copies of undeliverable/bounced emails.

Emails for the domain will be held for up to 7 days. If you know that your server will be down for more than seven days please contact us. Without special arrangements, our server will automatically return emails to the sender if they are not delivered within 7 days.
