I cannot login I don't have a My Cloudmark account

I can't add my Yahoo! email account to Cloudmark DesktopOne.


When adding a Yahoo! email account to Cloudmark DesktopOne, you may encounter the following error:

Wrong account name and/or password. The server responded: -ERR [SYS/PERM] pop not allowed for user..

In order to use Yahoo email with Cloudmark DesktopOne, your Yahoo! account must support POP. Free Yahoo! email accounts do not support POP.


To solve this problem you must upgrade to Yahoo! Mail Plus. See the Yahoo! Web site for more information:
