HTML files as attachments

I have a mailing list and some of my users attach HTML files.

I want MHA to show these attachments as links (like it does with binary 
files), and not to inline them in the body of the message.
(This is a "site builders" mailing list and users sometimes attach HTML 
files for other members to review.)
TIA.
