Mail Backup and MX Backup
E-mail has become a mission critical service on the Internet – we have come to rely on guaranteed e-mail delivery. The Mail Backup Service gives you peace of mind by queuing your mail when your primary mail server is unavailable.

If you have not already done so, you must first configure at least one primary MX record for your mail domain.
After you have configured this record, your next step is to set up your MX backup records. When you enable the service, additional MX records are automatically added to the ClearCenter DNS system. These additional MX records are added with a low priority (100 or higher).
The MX Backup service has the following limits:
Please contact technical support if you require extensions on these limits.
A status report shows the number of mails queued on the backup servers. This information is updated in your online account every 15 minutes.
How It Works
When your mail server is offline, the ClearSDN mail backup servers will begin to queue your messages. When your mail server comes back online, our mail backup servers will automatically attempt to redeliver your mail. Delivery attempts are made every 5 to 30 minutes (this time depends on a number of factors including how long the mail has been queued).
