output of kmail with wrong signature

DHL an important logistics provider in Germany and Worldwide has a new service,
they sign their mails s/mime to avoid scams. This is very nice but fails with
KMAIL. The signature is shown as invalid. 

DHL answered as follows: 
vielen dank für Ihre Information.

Wir haben den Sachverhalt von der zuständigen IT-Abteilung untersuchen lassen.
Dieses Problem ist uns bereits bekannt und tritt vereinzelt bei älteren
E-Mail-Clients (zum Beispiel MS Outlook 2003 / Express) auf.
Diese E-Mail-Clients haben gelegentlich Schwierigkeiten mit der verwendeten
Technologie (hier: "nested multipart").
Wir arbeiten zur Zeit daran eine Lösung auch für diese Art der Email-Clients
bereitzustellen.


Now...I hope that we are not on the level of "older email clients like MS
outlook/express! They claim the reason is incapacity of the client side to
elaborate "nested multpart messages".
I think this is an important feature given the size of DHL. Other providers may
get more serious on signing too.
