You have to recurse into the MIME object yourself.  filter_message
is passed a Mailmunge::Context object $ctx.  You get at the
MIME::Entity object with $ctx->mime_entity.

Then you need to familiarize yourself with the MIME::Entity man page
and look at the methods for accessing sub-parts.  Also, you can look
at the code in Mailmunge/Filter/Compat.pm for an example of how
its filter_message method recurses through the MIME parts.  Most of
the real work is done by the private method _rebuild_entity in that
file.

That said, if Mailmunge::Filter::Compat is more convenient for you to
use than Mailmunge::Filter, by all means use it... it's not going to
disappear.
