Using SMTP mail in SMF 2.1.4

[LWillisjr]

On my SMF site I'm starting to run into issues with delivering mail to domains that now require email validation. After some research I found that my mail type is set to (PHP default) in the admin mail settings. I would like to change to SMTP, but not sure where to get the correct SMTP server name. There seems to be a default of 'smtpout.secureserver.net' but when I select this and do a test, I get error messages that the SMF can't connect. Any help pointing me in the right direction is apprecated.

Contact your host if you don't know. Usually you can set up email accounts in cPanel/Plesk/whatever control panel your host uses, then connect to "mail.yourdomain.com" with the email address and password you created in the control panel.
