Unfortunately, the Content-Length header has design flaws (to say the least!)
that render it one of the worst ideas ever inflicted in email.  Hopefully,
there aren't too many people left who are still deluded into thinking that
Content-Length is reasonable; so I won't go into the long "why Content-Length
is hardful" lecture...  ;-)

As Mike observes, the correct thing to do is to "from-stuff"; that is, insert
a ">" prefix to lines that look like the internal "From " line, *NOT* "all
lines that start with "From ".  For sendmail, it's the F=E local delivery
mailer flag.

dtmail is also being unreasonable by including an internal format line in a
forwarded message.  Presumably, this is a vestige of UUCP thinking, since the
alternative explanation involves a contempt of Internet standards, and we all
know that SUN would never do such a thing, right?  ;-)  ;-)
