I think you'll have to write your own.
At minimum you need a full mail message parser so that you are not
filtering, say, base64 or QP content incorrectly. So something which
scans a mailbox and for each message:
- decodes it completely
- applies your filters
- assembles the new message
and write this out to a new mailbox (so it isn't destructive and can be
compared to the original - you don't want to accidentally shred your
archive).
I'd do this in Python myself - it has a good email library and you can
do all the things you describe fairly easily with it.
