Having problem sending mail using PHP and apache

[Karuna]

Hi everybody,
I have been trying to write a simple mail script using PHP and apache on Windows XP. Eventhough the script is saying that the mail is successfully sent, I am unable get it in my mailbox(I have given my mail address in $to). I am using the mail() function and I have made the following changes in php.ini

[mail function]
; For Win32 only.
SMTP = localhost

smtp_port = 25

; For Win32 only.
sendmail_from = [e-mail]

Can anybosy help me with this?

Welcome to WebmasterWorld Karuna,

do you have an smtp server on your local machine?

I have it this way

SMTP = mail.myisp.net
