php mail not working on rackspace cloud

Question

i have this rackspace server, and i installed sendmail there. the sendmail is configured to send emails using sendgrid.

so the sendmail works via the terminal, but the php mail function returns false, and doesnt send any emails. the sendmail path is correctly set in the php.ini too.

I have this in the /etc/php.ini,

sendmail_path = /usr/sbin/sendmail

when i take a phpinfo() using

<?php

phpinfo()

it returns

sendmail_path = /usr/sbin/sendmail

two quick ideas: reload your config file and double-check your permissions — Cameron, Mar 12 '12 at 09:16
Verify you're using the `php.ini` that you are editing, when `phpinfo()` shows, check the `php.ini` is showing as `/etc/php.ini`. Failing that, this question might get more answers on serverfault.com — MrCode, Mar 12 '12 at 19:13

From http://www.rackspace.com/knowledge_center/article/how-do-i-test-php-smtp-functionality here's the code they refer to use in order to get your mails working on the Rackspace Cloud Sites...

Non-SSL

<?php
require_once "Mail.php";


$from = "Web Master <webmaster@example.com>";
$to = "Nobody <nobody@example.com>";
$subject = "Test email using PHP SMTP\r\n\r\n";
$body = "This is a test email message";

$host = "mail.emailsrvr.com";
$username = "webmaster@example.com";
$password = "yourPassword";

$headers = array ('From' => $from,
  'To' => $to,
  'Subject' => $subject);
$smtp = Mail::factory('smtp',
  array ('host' => $host,
    'auth' => true,
    'username' => $username,
    'password' => $password));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
  echo("<p>" . $mail->getMessage() . "</p>");
} else {
  echo("<p>Message successfully sent!</p>");
}

With SSL

<?php
require_once "Mail.php";

$from = "Web Master <webmaster@example.com>";
$to = "Nobody <nobody@example.com>";
$subject = "Test email using PHP SMTP with SSL\r\n\r\n";
$body = "This is a test email message";

$host = "ssl://secure.emailsrvr.com";
$port = "465";
$username = "webmaster@example.com";
$password = "yourPassword";

$headers = array ('From' => $from,
  'To' => $to,
  'Subject' => $subject);
$smtp = Mail::factory('smtp',
  array ('host' => $host,
    'port' => $port,
    'auth' => true,
    'username' => $username,
    'password' => $password));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
  echo("<p>" . $mail->getMessage() . "</p>");
} else {
  echo("<p>Message successfully sent!</p>");
}
?>
