note 25120 added to ref.mail

I been on Windows network & have configured one of my Windows Server to run PHP & Apache. When i send an email using the mail() function, i got the server error message. So in my PHP.ini file, i edited the SMTP to the IP address of my server with port name. i.e. 12.2.0.1:25 but nothing happened. Any idea, how i can send email from Apache +PHP Windows server while in the network? -- http://www.php.net/manual/en/ref.mail.php http://master.php.net/manage/user-notes.php?action=edit+25120 http://master.php.net/manage/user-notes.php?action=delete+25120 http://master.php.net/manage/user-notes.php?action=reject+25120
