VM (mail reader under XEmacs/Emacs) does this.  In my emails, I see the=20
following header:

X-VM-v5-Data: ([nil nil nil nil nil nil nil nil nil]
        ["442253" "Friday" "25" "May" "2001" "09:31:43" "EDT" "Tamrof@aol=
=2Ecom"=20
"Tamrof@aol.com" nil "6082" "FML #406 - Space invaders" "^From:" nil nil =
"5"=20
nil "FML #406 - Space invaders" nil nil nil] nil)

and it adds this header for every email.  I can provide more examples if=20
needed.  I don't know if it does it for imap emails or not.  I suspect it=
=20
does.
