Generally there's little reason to run a secondary MX. Email will queue if the sole MX is offline or unreachable. Email will queue at senders' mail servers.
The problem with the above is that your (or your users') email delivery is then dependent upon the configuration and timeouts of someone else's system (my system drops undeliverables after 1 hour). A backup mx system gives you the capability of getting and keeping what you can, when you can. What you do with it after that is all under your control. -Jim P.
