"Right" is what the server's administrators want. Not what anyone else
may think they want. (Of course, they may screw up their config so that
the server doesn't do what they want, but that is their problem.)
In our case, if our server sends a 550 for an overquota error, we want
the message to be bounced back to its sender because we haven't been
able to deliver it for several days. We don't want the sending server
to retry - which would most likely just lead to another delay before
bouncing (and waste resources in the process).
