Problems with mail() function

[sabbagh]

RedHat 7.3
PHP 4.3 as a module
Apache/1.3.27
Postfix

I just want to execute a simple mail() function but I get a message saying:

Fatal error: Call to undefined function: mail()

The code is here

<?php

$to = "[e-mail]";
$subject = "mailTest";
$message = "This is a Test!!";
if(mail($to, $subject, $message))
{
echo "<h3>OK</h3>";
}
else
{
echo "<h3>Error</h3>";
}

?>

If i try this:
$mail -s "blah" [e-mail] < /etc/passwd

it works fine.

I can't find my php.ini but the phpinfo() says that the sendmail_path is just: -t -i

Any suggestions??

The path to sendmail should be something like /usr/sbin/sendmail -t -i

or wherever it is located on your box.

but i can-t find php.ini
even with
locate php.ini
or with
$cd /
$grep -r "sendmail_path" *

i don't know where to change this path.....

Hi,

Did you ever manage to find out what was the cause of your problem and how to fix it?

As I have ran into the same wall on this one.
