I am trying to re-create items in a mailbox which have been archived and than deleted.

If an item contains recipients of post offices that do not exist anymore createItemRequest fails with status: "D103: Post Office not found".

Is there a way to prevent this "recipient check" on createItemRequest? The described case will appear very likely in an archiving scenario.
Removing the "invalid" recipients is not an option. The mailbox owner needs to know the recipients of an email even if they do not exist anymore.
