So you also want to add support for the split operating directly during
saving new mails?

I guess you can copy&paste most of the code from zlib-plugin.c and just
implement a new ostream. ostream-bzlib.c should give a good example. You
just need to implement:

 - sendv(): this works similar to writev() syscall. Here you need to
keep read the input bytes and track when the message header ends and
write to different files before/after that.

 - flush(): If you do any buffering, flush it here.

That's about it. Much simpler than istreams!
