content filtering: replacing deleted parts with a warning

[Nathanst - SourceForge]

The Mailman content filter currently strips out
forbidden mime-parts from a multi-part message without
any trace and with no warning.

It would be nice to have a configuration option that
tells the filter to replace any deleted part with a
text/plain part which says something like "The message
part originally found here had a forbitten MIME type
xxxx/xxxx, and has been deleted."

(That way, when users try to send attachments they'll
at least know why the attachment isn't there any more.)

Thanks.
