Cool script, thank you for sharing.

Give me error "Set $_GET['email']." Why? Thank you

I'm also getting this Set $_GET['email'] message. Any idea?

Thanks in advance

This script doesn't have HTML form to accept the recipient email address. So you can test this script by passing GET parameters.

http:///yourhost/mail-test.php?email=[email protected]&send=true

Thank you. It's very useful.

Yeah awesome script, I use it like this.

http:///yourhost/mail-test.php?email=[email protected]&send=true

So the above sends an email to this mail tester and you get a response back with the details of your configuration.

how about enabling SMTP authentication?
