[PHP-INSTALL] [PHP-WIN] SMTP server response: 530 authentication required

[ciberflash]

The full error is as follows: Warning: mail(): SMTP server response: 530 authentication required - for help go to http://help.yahoo.com/help/us/mail/pop/pop-11.html in c:\program files\apache group\apache\htdocs\send_simpleform.php on line 10 I receive the error above when I attempt to send mail via a PHP script. From what I have read the PHP mail() function does not support Authenticated SMTP, just uses SMTP on the localhost, or that configured in the PHP.ini file. What I was reading suggested to use the PEAR functions. Hm... after looking that the functions PEAR provides PEAR may not work on a WIN machine. OR maybe I don't understand what I have read. Yep I am learning PHP. How do I get around this situation?
