Mail function problem Windows 2000

Hi folks Thanks for the responses to my mail yesterday. My situation is now this: I have a simple PHP script that just tries to send mail to myself. I have installed PHP 4.02 on both a Windows NT machine AND our new Windows 2000 server. The php.ini file is the same on both machines. The SMTP line refers to our smtp server which resides on a UNIX box. The script works on NT4 but not on W2K. The error I get is just 'Unknown error in <b>E:\new_email.php</b> on line <b>31</b><br>' where line 31 contains the mail function call. Is anyone else working ok with this on W2K? If so, maybe there's something I need to configure for W2K that I have overlooked? In either case, any help will be greatly appreciated!
