OS X Server and php.ini file

hi all, simple question probably, but i've installed php4.0b2 on my OS X server, yet can't seem to edit the php.ini to let me use sendmail...on os x files aren't located where they normally should be all the time, and to make matters worse, there's php3 floating around...however, everything works fine (except sendmail)...i made the typical test.php script, and it shows everything fine...no value for sendmail...in my php.ini file that's located in /usr/local/lib i have the sendmail line configured as follows: sendmail_path = /usr/sbin/sendmail -t i know the path is correct, i've checked it...i feel like it's not rereading the php.ini file...i've edited every .ini file i can find that has that sendmail line in it, andit just doesn't seem to bring it up....any ideas?
