Your error says basically the email address you are sending to doesn't exists, Recheck the address and spelling making sure they are correct. also check for a space you may have inserted before the recipient's user name in the email address. I have found that problem on customers' machines when I owned an internet service. If spelling is correct and no spaces or periods in the address then confirm the proper email address with the recipient.
