Why would your users submit mail to the backup MX host?

You're correct, they woudn't. I just don't like the thought that
someone could connect to the backup mx and pretend to be from my
domain. However, as I've just found out, since the backup mx is
"relaying" to primary, the primary mx bounces an email back, so I
guess the email won't be delivered anyway, however the queue gets a
MAILER-DAEMON messagage...
Actually, the MAILER-DAEMON message doesn't get queued at all! It just
discards it when it can't find the user (If the from address was
notarealaddr...@mydomain.com). So I guess it all good...
