It's reasonable to retry a host if you can make a connection to it,
but cannot talk SMTP to it.

No, it comes down to the weight you put on the importance of sending
mail to the primary vs the secondary MX.  If you think it's important
to talk to the primary, then you'll retry successful connections to the
primary.

Since you seem to think that any temporary failure means that the
secondary MX should be retried, what about a 4XX failure?  Should that
cause the secondary MX to be used?
