Which doesn't follow at all, as MMDF is also using in-band data as
a separator, just a different one.
Back when I made the decision it was out of band.
I never really used MMDF format, so I am not sure of its details, but
as I understand it, the only real issue with mbox format is that the
conversion isn't invertible, that is, in that format, a line that used
to start "From" is stored as ">From" (which exact lines that happens to
depends upon implementation to some extent, but that doesn't matter),
whereas an input like that started ">From" is also stored as ">From".
When it comes time to extract the message, there's no way to invert that
addition of the '>' as there's no way to determine whether the '>' was
one that was added for this purpose or not.
Exactly, but if SOH*4 is now in band, it looks like I now have
to redesign my archive scripts.
