PHP script for sending mail won't work when executed via browser but work fine when executed from command line

Question

I've written a little PHP script:

<?php
$phpPath = shell_exec("which php");

print "$phpPath\n";
 
$uid =  posix_getuid();
$userinfo = posix_getpwuid($uid);
print_r($userinfo );
print "\n";

    $to = "my_user_name@my_company_mail.com";
    $subject = "Test mail";
    $message = "Hello! This is a simple email message.";
    $from = "do-not-reply@akamai.com";
    $headers = "From:" . $from;

    $res = mail($to,$subject,$message,$headers);

    print_r(error_get_last());
    if($res){
    echo "Mail Sent.\n";
    }else{
    echo "Mail was'nt Sent\n";

    }
?>

The thing that drives me crazy is that when I execute this script from command line it work fine:

/usr/bin/php

Array
(
    [name] => daemon
    [passwd] => x
    [uid] => 1
    [gid] => 1
    [gecos] => daemon
    [dir] => /usr/sbin
    [shell] => /bin/sh
)

Mail Sent.

but when I execute it from a remote browser this what I get:

/usr/bin/php

Array
(
    [name] => daemon
    [passwd] => x
    [uid] => 1
    [gid] => 1
    [gecos] => daemon
    [dir] => /usr/sbin
    [shell] => /bin/sh
)

Mail was'nt Sent

any idea?

Command Line PHP and PHP doesn't use the same php.ini, please check if you have difference between them.
