That is only if you client also sends a text variant in a multipart
mime encoding. I believe mailman may still accept those and expand the
text portion.
To quote the mailman docs:
----------
After this initial filtering, any multipart attachments that are
empty are removed. If the outer message is left empty after this
filtering, then the whole message is discarded.
Then, each multipart/alternative section will be replaced by just the
first alternative that is non-empty after filtering if
collapse_alternatives is enabled.
----------
Allowed mimetypes:
multipart/mixed
multipart/alternative
message/rfc822
text/plain
But to answer the "reason" part - we get periodic spam on these lists
and the only ones that seem to sneak through are HTML. That's where
the idea came from, so I asked the rest of the devs about blocking
html mail and got an emphatic "please do it!" from all of them - thus
it was done.
HTML email will be rejected
