I can give a few implementation hints:

With v1.2 you should be able to do this completely in a plugin, because
maildir saving keeps the output stream in struct
mail_save_context.output. You could hook into mailbox.save_begin() where
you'll first call the super.save_begin() and then replace the created
output stream with a zlib_ostream, which you'll need to implement.
Currently the only implemented output stream is src/lib/ostream-file.c.

Actually it sounds like it would be pretty easy to implement after the
zlib_ostream is done. I thought it would have been more complex. :)
