Server Error: 501, Error Number: 0x800CCC79

I try to send an email to the following address *** Email address is removed for privacy *** I get this message. The message could not be sent. The authentication setting might not be correct for your outgoing e-mail [SMTP] server. For help solving this problem, go to Help, search for "Troubleshoot Windows Mail", and read the "I'm having problems sending e-mail" section. If you need help determining the proper server settings, please contact your e-mail service provider. The rejected e-mail address was'*** Email address is removed for privacy *** '. Subject 'Fw: anyone with kids, a must read!', Account: 'POP3.mail.wowway.com', Server: 'smtp.mail.wowway.com', Protocol: SMTP, Server Response: '501 5.5.2 RCPT TO syntax error', Port: 25, Secure(SSL): No, Server Error: 501, Error Number: 0x800CCC79. I get this message only on this address. everything I read says it is a smtp server error. My ISP says it's a Microsoft issue. Can you help.

I found the error. Windows Mail adds the name at the begining of the email address. It was a long string of characters hat my ISP didnot like.

The error message mentions Windows Mail. Is that what you are running in Vista? This is an XP Files forum.
