See SAVE_MSGS_AS_PICKLES in Mailman/Queue/Switchboard.py for whether
re-queued messages get stored as a pickle or as plaintext.

See METADATA_FORMAT in Defaults.py/mm_cfg.py for the storage format
for the metadata dictionary (I was mistaken that it's always a pickle,
in fact it's usually a marshal, and METADATA_FORMAT=METAFMT_MARSHAL is
probably the only one that works, see SF patch #567288).
