Redelivering mail from archive (mbox format? to Maildir)

[PenguinWhispererThe .]

Hi,

A user had an issue with his mail software and got some emails deleted.
I can't seem to restore them from backup however I found the email in the
mailscanner archive directory /var/spool/MailScanner/archive/.

However I don't seem to find how to "replay" this message. So let it be
delivered in the Maildir again.

I found some articles about quarantined emails and I have these settings:
Quarantine Whole Message = yes
Quarantine Whole Messages As Queue Files = no

So if I understand this right I have emails in Mbox format in "archive"?
Filename is something like this:
E124D123456.A123F

How can I let this archived message be delivered again to the Maildir of
the user? The user Maildir is on the same server. So perhaps there's a way
to put it in a correct directory in the Maildir or put it in a queue. Or is
it in like an EML format?
Or is this not possible?

I'm using postfix BTW.

Thanks in advance for your help.
