UTF8 problem with Microsoft Exchange and Mailman 2.1b4

Hi,
I have a problem with UTF8-encoded e-mails from a Microsoft Exchange 2000 server which are sent to a Mailman 2.1b4 mailinglist server. Exchange uses "utf8" characterset, so that the users will get an extra "attachement" with every mailinglist message (charset "utf-8" is used for the body, and charset "us-ascii" is used for the signature of the mailinglist).
An example of the headers and body is included, below.
Is there a way to change the filtering in Mailman, so that these messages are converted to a more common charset, such as: us-ascii or iso-8859-1
For more information see: http://www.microsoft.com/exchange/techinfo/tips/Mail_utf8.asp (Mailbox Tip: Allow Non-UTF-8 Mail Clients To View Messages Sent from Exchange). I tried to get the Exchange server changed, but didn't get any response of the local administrator. ;(
Regards,
Pieter
