An unknown error has occurred. Subject ‘Test Sending 18 Mar 2004′, Account: ‘mail.yourdomain.com’, Server: ‘mail.yourdomain.com’, Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0B

I am getting this error message. What can I do ?

This is most often a problem with your email client, not cpanel, you need to turn on “My Server Requires Authentication” if you are using outlook you can find this option here:

tools > accounts > [choose account] > properties > servers

You can also follow the tutorial here to enable outgoing SMTP authentication.

Another common reason for this error is that the recepient ID is invalid. Delete the mail in your outbox, create a new mail and check the recepient ID.
