    The problem is in the SMTP sender at the Symbolics end.  There is a
    bogus space after "MAIL From:" before the "<" that begins the return
    path.  RFC 821 is quite specific about where spaces are expected and
    where they are not expected.  You cannot say "MAIL FROM: <FOO@BAR>",
    you must say "MAIL FROM:<FOO@BAR>".

    TOPS-20 isn't the only SMTP server that is fussy about this.  Even some
    Unix-based servers insist upon compliance to the spec here.
