This issue (or a related one) has come up before
Generally it seems to be caused by tools that add mbox 'From ' headers,
without actually mbox escaping the file. We haven't yet reached
consensus on a good solution (generally people just want to fix their
own mail, which is understandable). A workaround discussed in the
messages I reference above is to strip the 'From ' header before passing
to notmuch-insert. Perhaps some scholar of the RFCs can convince us that
that is "always" the right thing for notmuch insert to do.

I'd be worried about letting notmuch-insert deliver messages that
notmuch-new would not be able to parse. In particular we'd like to keep
the property that a Maildir + the output of notmuch-dump should be
enough to completely recover the notmuch database.
