So the email client doesn't find out that there are two servers he can try.
But, a question aside, because probably I misunderstood the functionality of a backup MX.
Shouldn't it be possible with this setup to:
- If someone sends an email to info[ @ ]rackster, his mailserver checks if my 1st server is up. If yes -> send to it, if no -> send to the 2nd. As soon as the 1st is up again, 2nd -> sending to 1st -> to the email address finally.
- If I want to send an email, check if 1st server is up -> if not, send via the 2nd.
