The above is not correct. If you have a single word as a
pass_mime_types (or filter_mime_types) entry, it is the main type, not
the subtype. So, if you want to pass multipart/mixed and
multipart/alternative, that's what you need to put.

I recommend however just putting


in pass_mime_types. These, together with collapse_alternatives = Yes
and convert_html_to_plaintext = Yes will ensure only plain text
reaches the list and will also accept the plain text from messages
that have a structure like


which are produced by some Microsoft MUAs and possibly others. If you
don't pass multipart/related, that entire message will be filtered. If
you do pass all multipart and collapse alternatives, only the
text/plain part goes to the list.

Yow might also consider adding message/rfc822 to pass_mime_types if you
want to accept plain text or converted html from an attached message.
