I've chatted with him a few times (I'm a Dovecot user and fan).

Would someone like to take a crack at implementing this format either in, or
on top of, the Python stdlib mailbox module:

I'd much rather use something standard (and maintained by someone else!) than
a bunch of custom code specific to Mailman.
