Two Received headers and the X-Virus-Scanned would amount to some 400 
characters, with an additional X-Spam-Status the header size sincrease
could be belong 700 characters. So I guess this looks normal and
seems to indicate that body was not duplicated in this case, at least
not in Postfix and not in amavisd.

I doubt it. I'd concentrate on a mail delivery program (procmail???)
or user agent. For the above case, see also what was the mail size
in the user's mailbox.

I doubt the problem lies there.
