Outlook email configuration problem

Hi:

I’m trying to configure Outlook to send and receive emails from my domain, but have been unsuccessful.

I installed the RoundCube script. My virtual domain is receiving and sending emails within RoundCube without issues. But, I cannot get Outlook to work.

I’m getting:
“The server for account “Test Account” returned the error “Authentication failed…” Your username/password or security settings may be incorrect. Would you like to try re-entering your password?”
and
“Outlook cannot find the server. Verify the server information is entered correctly in the Account Settings, and that your DNS settings in the Network pane of System Preferences are correct.”

I am sure that the password is correct.

My Settings are:
incoming: mail.mydomain.com Port 110
outgoing: smtp.mydomain.com Port 25
username: myemail@mydomain.com
password: mypassword

Thanks!
