The server rejected your logon/login
Verify the email address and password, you may have made a typo. You can also check the password with us by logging into the webmail (manual: Mailing via Webmail).

The host "<host name>" cannot be found

In this case, the incoming and/or outgoing server is not correct, check that you have performed step 8 correctly and that the domain is registered in the DNS Zone (Add a domain to DNS) and that you have waited at least 2 hours for newly registered or transferred domains.
