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.
