Unable to Send Over Port 25 with GoDaddy

This article applies to recent versions of SmarterMail. View articles for SmarterMail 15.x and earlier.
System Administrators who utilize GoDaddy as their server provider may experience trouble sending mail over port 25. This is because GoDaddy requires their servers to send through their SMTP Relay. This requires an outgoing gateway in SmarterMail with GoDaddy's specific settings. More information on their server's email relay settings can be found at GoDaddy's Help.
For steps on creating an outgoing gateway with SmarterMail, please see Configure SmarterMail as a Free Gateway Server.
