Is 'your' queue better than everyone else's? Why not do a 4xx tmpfail

Why bother even having a backup MX if all it will do is return a 4xx? Why
not let the sending server just fail to connect you your server and it
will retry just as long before failing.
You might want a backup MX or multiples that can run concurrently in
case one of them has problems and the other(s) can provide equivalent
relay service. However, this situation involves the primary delivery
server or the authentication mechanism used to test for valid users.
You can't deliver in any case. What's the point of accepting it then?
My point of view may be skewed by getting about 50,000 dictionary attack
attempts daily for the last few years, but accepting mail without
knowing the address is valid is not healthy. You are just asking to
overwhelm your own outbound queue with NDN's.
