[Dovecot] Bounce vs. Defer

Hello--

I've noticed that with when using deliver, if there is a misconfiguration in my dovecot configuration file, a permissions problem on the maildir, etc., deliver will bounce the message. I'm using Postfix, and at some point used Maildrop, and I know that maildrop (and I believe also Postfix's virtual transport) instead defer the message if there is some kind of fixable problem (like permissions). Then, when the problem is solved, you can flush the queue.

Would it be possible to add a defer option to deliver? It makes it difficult to try out new options or different configurations because if you have fairly regular incoming mail, the last thing you want is a ten minute period where 20 messages get bounced...

Thanks, Jeff
