  Most likely some of your recipient addresses are themselves mailing
lists which redistribute the mail.  If they send you a complete copy
of the mail you might be able to narrow this down by looking at the
'Received:' headers.  Then if you and the suspect destination are on
Internet, you can 'telnet' to the 'smtp' port and use the 'EXPN'
command to expand the address you are sendingto.
