How do I use BackupMX?
How do I setup BackupMX?

Solution:

To use the Backup MX service you need to make a simple change to your DNS and add the BackupMX servers at a lower priority (thats a higher MX number) than your primary mail server/s.

Example 1

Lets assume your domain is called example.com and when you look up your MX records you get back something like the below

example.com IN MX 10 mx1.example.com.

When you sign up for the BackupMX service you will be allocated to a mail server. In this example the BackupMX server is called mx44999.smtp-engine.com.

All we need to do is add that server with a lower priority (higher MX value) to the list. So our MX list will now look like this

example.com IN MX 10 mx1.example.com.

example.com IN MX 20 mx44999.smtp-engine.com.

And thats it!! You're all done.
