    I am able to log into webpage and send mail .Can anyone tell me how to get my outlook to not get the following message from yahoo mail server :-An unknown error was returned from the SMTP server. Subject ‘****’, Account: ‘pop.mail.yahoo.co.uk’, Server: ‘smtp.mail.yahoo.co.uk’, Protocol: SMTP, Server Response: ‘521 yahoo.com closing transmission channel. Remote IP is over the limit for messages allowed to be sent in a single day.’, Port: 465, Secure(SSL): Yes, Server Error: 521, Error Number: 0x800CCC61


  • Richard J Try this and see if it helps you Open Outlook Tools Accounts Mail tab Click properties Advanced Tab

    Add a check to “This server requires a secure connection”

    It is happening to me and many others, it must be a Yahoo problem ( again )
    I have got it working by unticking the SSL box in advanced tab of properties and using port 587.

    It seems yahoo doesn’t care, I’ve sent mails asking for help, and had nothing back, you are better off getting an MSN account, its much better.

    I have been having the same problem. Jim G solution of using 587 in the stmp advanced tab seems to work. cheers Jim
