[Mailman-Users] Blocking MS-Word attachments

[Steven Massey]

Perhaps I have this setup incorrectly, but I want to block attachments 
to my listserv and so I'm stripping the following mime types out of all 
messages:

image
video
application

Then I have the conversion to text/html set to yes.

Nevertheless, MS Word files that are under my maximum message size 
limit seem to slip through.  Is there a mime-type I am missing?  I 
thought MS Word would fall under the application category.

Thanks,

Steven Massey
