Settings to send email from localhost for PHP code in Windows Vista [duplicate]

Settings to send email from localhost for PHP code in Windows Vista [duplicate]

I am using PHP 5 and Apache to do some programming. My code can correctly send emails on the live server, but on my own development machine, I cannot send emails. There is obviously nothing wrong with my code (since it only fails to send the email on my development machine), so I guess the problem is with my settings.
