If this is a nonexistent mailbox, the mail server should refuse to accept the message, and return it as undeliverable, and maildrop should not even be run.

The problem is with virtual users, where only Courier-IMAP knows which users exist and which not. Coupling Courier-IMAP with non-native MTAs requires more or less beautiful "hacks" to make the users known to the MTA.

What do you think about an option for Courier-IMAP to make unknown user a temporary failure? There are people out there who _can_ make this concious decision. :-) This problem pops up every few days/weeks here on the list...
