SMTP 520 authentication error

[carnage]

Hi I am trying to configure mail() in xampp and I cant get it to work, I have set SMTP to mail.btinternet.com and port is set to 25 and now it comes up with this message
'Warning: mail() [function.mail]: SMTP server response: 530 authentication required - "Your email could not be sent. To fix this you must make a simple change to your email (known as SMTP authentication). For advice visit www.btyahoo.com/smtp"'

I have been to the advice website and followed the instructions which don't really make sense( i cant do it automatically because I am using Win 7) and it still doesn't work

How can i get it to work?
Any help is appreciated
Thanks,
Matt

You cannot use the standard PHP mail() function, if the specified SMTP Server needs basic authorization. PHP mail()does not support authorization.

You either must setup a local SMTP Relay (like Mercury SMTP Relay), which relays the mail to remote SMTP Server and supports authorization, or use a sophisticated mail class (instead of mail() function) like the phpmailer class from phpmailer.sourceforge.net

@ aj123cd
The OP requires authentication but this is not possible in the links you posted as outlined in Nobbie's post.

@ carnage
There is an alternate solution included in XAMPP that you can use and I have linked below a search that may provide the answers:
