When one uses the UNIX "mail" command to forward messages, if the
text contains a line beginning "From" then it is prefixed by ">"
in order to avoid looking like a message header to "mail" at the
receiving end.  (At least, the System III mailer works this way.)
I believe this to be acceptable behavior, since no message should
contain TWO "From..." lines.  Sorry if your mailer is broken.
