The explanations on mailman's "Content filtering" page are sadly rather
unclear about details, and about how the options interact.

I've used it in the past, and just assumed it did something sensible.
A bit of googling suggests that it just takes the first part (which
is usually text/plain but doesn't have to be).

But since multipart/alternative with HTML and text versions in reality
always has one auto-generated from the other, it doesn't really seem
too important which happens.

I don't think there's an official type, but text/x-patch is common.
Attachments of text/x-c, text/x-perl, and several other text/x-* types
should probably not get stripped.  If you go that route, I'd probably
suggest allowing text/* with a few exceptions, and stripping anything
else.  

Incidentally, I don't think the recent rash of messages is an attempt to
spam.  Several of the posters seem to be trying to write a GIS system
which uses Xapian:
