Sendmail - SMTP server response: 503

hello
I have purchased a dedicated server to run some php scripts and have setup a program called xampp.

I turned off IIS and started the default IIS smtp server.

I can't send email using php.
I keep getting: Warning: mail() [function.mail]: SMTP server response: 503 This mail server requires authentication when attempting to send to a non-local e-mail address. Please check your mail client settings or contact your administrator to verify that the domain or address is defined for this server.

I had a look in the IIS SMTP server parameters and it indicates the authentication access is set for anonymous.

PHP Code:


		
			
 ini_set('sendmail_from', 'me@domain.com'); 

error_reporting(E_ALL);

ini_set('display_errors', '1');

ini_set('smtp_port', '25');

ini_set('smtp', xx.xx.xx.xx);

    

if(mail('peter@mydomain.com','test subject','test message')){      echo('ok');    }else{      echo('not ok');    }

Do I need to setup anything else??
help please

I have recieved some support from the ISP, but I am still struggling...

I was told not to use the SMTP IIS server and use the 'mailenable' software installed.

I am TOTALLY unfamiliar with it but I gave it a go and it is still not sending mail outside the server domain name.

In 'messaging manager', I have 'enabled integrated authentication'.

In the post office, I also use 'integrated authentication' and I map the post office to my domain name.

I have setup a mailbox.
the disgnostic is telling me my post office requires windows authentication so I am guessing it's correct.

...but it still fails

I assume you have given up on this.

Here are things I would do different.

Do not use MS server software for your xampp (great package btw)

Use an external SMTP server. I get a hosted domain and just use the email server.
They can deliver your mail through more spam filters and you can test using some pop3 clients.
