Do these SMTP settings look correct for SMTP relay using XYZForms which essentially uses PHPMailer on the back end.
I keep getting an error no matter how many different combos I try for SMTP settings.
What type of hosting are you using?
With cPanel you use localhost as the server, no login, no ssl, on port 25
For other types of shared hosting, it's mostly the same, but you use relay-hosting.secureserver.net as the server.
I am using Deluxe Web hosing Linux with no cpanel.
I have set my application use port 25, notls, and authentication false and still get an error.

So it seems even on port 25 its can authenticate to the server.
