	I believe so, yes.

	Why would you do this?  What do you have in multipart/alternative 
that would require this kind of action?

	Yes.  Just list multipart/alternative as one of the formats to 
pass unchanged.  Go to "Content Filtering", then add 
"multipart/alternative" to the "pass_mime_types" field (the second 
big one on the page).  Note that you have to have filtering turned on 
for this to have any effect -- if you don't have filtering turned on 
(the radio button at the top), then no filtering should be done.
