Both of your questions have the same answer; you need to build up a
new MIME message in filter_end using the MIME::tools methods to
manipulate the message, and then call replace_entire_message to
replace the message with your newly-constructed message.  This lets
you do any sort of message-manipulation you can think of.

It's up to you to be careful and make sure you end up with something
sensible that doesn't cause failures in email clients that you care
about.  In particular, mobile clients may be very fussy about the
sorts of messages they display correctly.
