    From RFC 2822 (Internet Message Format):

       At the most basic level, a message is a series of characters. A
       message that is conformant with this standard is comprised of
       characters with values in the range 1 through 127 and interpreted as
       US-ASCII characters [ASCII].

    A NUL in a message body is not valid. That said, clearly neither
    Outlook nor Outlook Express should choke on such a message - I'm passing
    this information along to the appropriate people.
