mail function does not work

[Anon]

I continue to receive the same message
"Server Error in C:\WebSites\Terry\SendMailHeaders.php on line 41"
pointing on the mail function.
I receive it when running on Apache Server on IIS5.0 server on Windows 2000.
It seems that it cannot find mail function, although I installed rather recent version of php in January.

Whatever kind of email functions I am using I am receiving errors.
Even for this simple code I am receiving Server Error:
<?php
mail("[e-mail]","comments on newsletter",'Hi');
?>

I suspect that it is configuration problem, somehow nor mail function, neither imap_open are found by PHP.
