Your copy/paste of the web page is missing some information, namely,
which radio buttons are selected.

Generally, you don't want entries in both filter_mime_types and
pass_mime_types, since if you have anything in pass_mime_types,
everything else will be filtered whether it's here or not.

So you are accepting only elemental text/plain messages and text/plain
parts from multipart/alternative parts. This drops everything that
isn't text/plain and also drops text/plain subparts from other
For example, if you have a message with structure
which is a common structure for a message with an attached ms-word
file, you delete everything because you don't accept multipart/mixed.
What you probably want here is something like

This is probably irrelevant in most cases if you don't accept
text/html, but unless you want to actuall accept and pass say both
text/plain and text/html alternatives, set this to Yes.
>Should Mailman convert text/html parts to plain text? This conversion

This should be Yes, only if you accept text/html, and you set
collapse_alternatives to Yes, and you want remaining html parts
converted to plain text.
