mail() returning false in php

[dave_s_wang]

The following script doesn't work for me in php 4.3.9.

mail ( 'test@***.com', 'test', 'test');

I keep getting a return of false. i read some posts that said to change my php.ini sendmail_path = /var/qmail/bin/qmail-inject. but that didn't seem to fix it.

Any suggestions? Thanks in advance!
