[Mimedefang] Mimedefang + Outlook Invitation (text/calendar) issue

Hi mimedefangers,

CONFIG:

	latest mimedefang 2.48, standard /etc/mail/mimedefang-filter,
latest version as sendmail milter,
	sendmail 8.13.1 
	
	mimedefang-filter has 
	deactivated 	#remove_redundant_html_parts($entity);
	and activated 	action_rebuild();

PROBLEM:

	Outlook calendar invitations get mangled by mimedefang.
	A receiving outlook client reacts to by displaying the
text/plain or text/html
	part as e-mail text and showing the text/calendar
	part as attachment that can be opened. BUT it does not recognize
this as an invitation.

	It looks like mimedefang adds "Content-Disposition: inline"
	to the MIME parts, I could not check if this confuses exchange.

Has anybody experienced this before?

regs
Tom
