That's not possible because Postfix needs to be able to move messages
between queues atomically, i.e. with rename() rather than by copying
data from one file to another.

It is not perfectly clear to me what you are trying to do with
smtp_fallback_relay here. That would be an inappropriate tool for any
destination domain for which you have any specific knowledge.
