Uh-uh.  A "&" has an ASCII value of 26H or 38 decimal.  The MSB is definitely
set to zero, which means it is sent in 7 bits, like all the other printable
ASCII characters.  The OP's problem is probably that somewhere in the mail
handling chain, most likely at his machine, "&" is interpreted as a control or
command character, and not sent, thereby not getting the message to the
correct address.
