That's a relay error. It's actually a good thing. If your server is
setup to allow sending email without logging in, that's generally
called an open relay. That's where spam comes from. You can configure
your mail server to allow relaying from only the local machine. Then
you wouldn't have to login before sending mail. But you should only do
that if you really know how to configure your server. And if you really
know how to configure your server, you probably wouldn't do that.
You should look into another PHP mail function, like the PHPMailer
class library. This will allow you to authenticate with the mail server
before sending email. Then you won't have to create an open relay.
