I don't know, I never used this method of getting email in mbox
format.

No, "From:" (with the colon) is just an email header.  That's not the
line that needs to begin each emacs.  You need a line that says "From"
without the colon.  It sounds like such a line is completely absent
from your file, in which case Rmail will not be able to process it,
because that's how it knows that a new email message begins.

I think in your case using Gnus is indeed the right idea.
