How do I send the news letters out it is saying that at test email can't be sent

I am trying to use the e-newsletter and I must not be doing something right. What user name and password am I supposed to be using?
I use Godaddy for my hosting, am I supposed to use my password from that?
What am I supposed to use for the SMTP server and password?

Email Sending Method: HelpSMTP (recommended) HelpPHP mail
From email:
