Indeed, ChrisA divined my intent--an attachment remover based on
various types of mime-type and size tests.  A cursory search didn't
turn up any pre-existing utilities that did quite what I wanted.

Perhaps my previous message about detecting mbox-vs-maildir-vs-mh
format mailboxes hinted at this.  Thanks to all who answered there
(though I encountered a possible bug, as Claws Mail doesn't put
a .mh_sequences file in what it claims are MH local folders which
causes issues with MH() http://bugs.python.org/issue22319 ).

So the goal is to keep the original message with highest fidelity
while still stripping out the undesirable attachments.

Thanks for your thoughts,
