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.
