I have Windows Mail/Vista. It has always run fine. Now every time I send mail with an attachment, the email is sent to the recipient 20 or 30 times! The # of sent messages is different every time. I tested it by sending mail to myself. When I send without an attachment it's fine. Antivirus did not detect anything. I cannot find any help online. Clients are getting very P.O.! Can someone help me with this?
