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. :)
