All of a sudden I cannot send email from my Outlook Express account. I get this error message.
An unknown error has occurred. Subject ”, Account: ‘pop.charter.net’, Server: ‘SMTP.charter.net’, Protocol: SMTP, Server Response: ‘550 Message identified as SPAM – Please visit http://www.charter.com/postmaster’, Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC69
My ISP says it’s a microsoft problem. Any help?
