    Because this would be wrong. A delivery agent performing final delivery
    to mailboxes must do so *atomically* for each queue file recipient,
    because Postfix will either consider the delivery successful or failed
    for each queue file recipient, there is no "half-delivered" state.

    If the delivery involves storing the message in multiple mailboxes, there
    is a strong possibility of partial success (quotas, file size limits, ...)
    so each mailbox needs a separate recipient in the queue file, i.e. use
    virtual(5) to expand and then virtual(8) or similar to do 1-to-1 delivery.
