you should not reject the mail immediately, it makes sense to retry the delivery when a user is over quota.

This is true in many cases, however if you have a large number of users, which means a certain percentage of those are over quota at all times, then your deferred queue gets quite big and can overload the queuing mechanism and cause a lot of problems.

Not with the current version of Courier. After the first message gets deferred, Courier refuses to accept any mail for the recipient, with a temporary 4xx error code, until this is resolved.

The end result is that if the user fixes the overquota situation quickly enough, no mail gets lost.
