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: http://docs.python.org/library/mailbox.html I'd much rather use something standard (and maintained by someone else!) than a bunch of custom code specific to Mailman.
