Help!!!

Hi I'm Giampiero. I have a little problem trying to send an email. My configuration is: Win2000 server + Apache + Php4 I've changed these lines in the php.ini file: ; For Win32 only. SMTP = localhost (or my mailserver) ; For Win32 only. sendmail_from = "my email address" When I try to send my email it tells me: Warning: Unknown error in c:\provephp\prove varie\send_mail.php on line 23 Line 23 is: mail($to, $subject, $mail_body); Could you tell me why? I can't understand. Thank you very much. Bye.
