GoDaddy settings that work for me are as follows:
SMTP Host: smtpout.secureserver.net
Encryption: None
Port: 80
SMTP Authentication: Yes
SMTP Username: the user name (complete e-mail address) of the GoDaddy e-mail account that you are using to send
SMTP Password: the password that you assigned to your GoDaddy e-mail account
I have had problems with the GoDaddy e-mail accounts that are included with domains and hosting plans. I’m not sure why, but GoDaddy Workspace e-mail accounts are more reliable. Test your GoDaddy SMTP Username and SMTP Password at https://email.secureserver.net to be sure that they are correct before entering them in the Easy WP SMTP configuration.
