How do I set up the e-newsletter with email service

I am trying to setup the e-newsletter plugin to work with mailchimps mandrill email service, and cannot get the smtp working. When I send the test email.

"Failed to send test email! - Please check your outgoing email settings and server config to see if the selected ports are open. rror details: The following address failes: : Called Mail() without being connected"

Do you have a guide to setting this service up?

I am using as my host, and they use cPanel for set up.

Any help would be appreciated.
