I think he wants to keep the mbox format, so that each part is
readable by elm, or even mutt.

Wash, if that's the case, then formail(1)  (included with procmail)
will split up one big mbox file into smaller ones.  Heck, if you
want a small programming exercise, awk or perl could even do it.

If preserving the mbox format is not important (i.e. ignoring
"^From " lines), then the aforementioned dd(1) or split(1) will do
the trick.
