Well, this is a tough call.  I use pmd as my delivery agent, and it
delivers my mail in rmail format and incidentally quotes rmail message
delimiters.

This issue came up ages ago in various forms.  It seemed that an
adaptive algorithm was useful (to allow reading of mail in various
formats).  Of course, it can get confused by this sort of thing.  The
original reason I came up with the adaptive method is that packf (an mh
utility to pack messages) puts its output in mmdf format (1 line of 4
C-a's on each side of a message) and we didn't want mh users to have one
more area of confusion when converting to rmail.  In the process, it
seemed to make sense to make rmail-input understand rmail format; it's
more efficient, since no editing is done on input.  Of course, there are
nasty cases, such as this.  One compromise was to have rmail look at the
first message in a given inbox and parse the rest of the file according
to that.  Unfortunately, it's possible to use rmail-output and
rmail-output-to-rmail-file to create a mixed file, and it's nice to be
able to convert it back.

BTW, From gets quoted by /bin/mail or in some cases sendmail (bletch!
MTA's shouldn't be doing things like this).  Unless you have a delivery
agent that understands what rmail is going to do (as pmd can be
configured to do), you're going to have problems of this nature.
