straight out of error_log
PHP Warning: mail() is not supported in this PHP build
um...yeah, wtf? it's PHP 4.1, downloaded on July 17 2002 (that's like 1 month ago) why is it telling me this?
Have a look in your php.ini file. Is your mail function set up? You should set the SMTP server and the address from which to send the mail.
You could always get the latest : http://snaps.php.net/win32/php4-win32-latest.zip for windows
or
http://snaps.php.net/php4-latest.tar.bz2 for *nix
ok i installed the latest and it still says it. mail IS configured. sendmail path is /usr/sbin/sendmail
