Hmm, any IMAP mail client I know has an option for exactly that feature.

I don't know postfix. I would look into the line:

Variant I
a) MTA adds envelope sender (aka MAIL FROM) to envelope recipient list 
(aka RCPT TO, aka BCC).

b) LDA delivers mail into Archive folder if the sender is the owner of the 
mailbox.

Variant II
as variant I, but adds an Header that helps the LDA to decide, if the 
mail has been sent by one particular user, e.g. the MD5 hash of the 
SMTP AUTH uid.

Variant III
a) MTA always adds a robot to the envelop recipient list.

b) This robot spools the mail according the From: header of the mail or 
yet another piece of information you can most likely aquire the sender 
from, e.g. authentification data. E.g. match the message ID or queue ID 
with the logs of the MTA.

Of course, in all these cases you need to decide beforehand, if the mail 
is inbound or outbound.

Bye,
