Some Yahoo! Small Business customers are reporting errors while sending or receiving Business Email using a POP client, such as Outlook, Outlook Express, Mac Mail, or Thunderbird.
If you are having trouble accessing your mail with POP, please ensure you are entering the correct POP settings for your account.
As a workaround, Business Email users with POP and Webmail access can send and receive mail using the Webmail interface. To access your mail, visit http://mail.yourdomain.com (replacing yourdomain.com with your own domain name). See details in the help center.
We are working toward a resolution as soon as possible.
