There is a basic design decision in content filtering that makes this
difficult. Namely, after filtering, only the first remaining sub-part
from a multipart/alternative part is retained.
What this means in practice is if you want to allow both text/plain
parts and text/html parts, the only way to get html to the list is to
insure that the MUA (e-mail client) that creates the post creates an
html only message, not a multipart/alternative message with both
text/plain and text/html sub-parts.
If you want Mailman content filtering to pass the html part from a
multipart/alternative post, the only way to do this is to disallow
text/plain and require everyone to post html, or to turn off content
filtering and allow everything.
