Well my settings include:
1. The email address I want displayed.
2. The from name I want displayed.
3. From User (my username)
4. Mail delivery method (PHP mail())
5. Path to sendmail (/usr/sbin/sendmail)
check the above with your host.6. SMTP auth username (My cPanel username)
7. SMTP auth password (My cPanel password)
And thats it. If you are still having trouble ask your host what options are available for your server. Some servers are set up differently than others.
HTH.
