I don't think its that simple. I've noticed several times spam software
injecting mails in the "fallback" mail servers, without ever having tried
the regular mx point.
I believe this is on purpose, often backup and failsafe servers are less
strict configured than the regular mx server. Since then I always make sure
that the backup server is always much stricter in SPAM checking :)
