This seems more hopeful to me than relying on Content-Length. I tried
(but failed) to quickly understand what GMime is doing to decide if
something is an mbox, but it seems possible that Jeff S (GMime
maintainer) might be receptive to something along those lines.

There is a GMIME_FORMAT_MBOX, but maybe something like
GMIME_FORMAT_RFC4155 could specify a stricter mbox format were each
"message" should be roughly RFC2822 formatted.
