Step #1 - Create Wrapper Script


vi /usr/local/bin/phpsendmail

#!/usr/bin/php
<?php


//changed by realtechtalk.com to make the log readable
/**
  This script is a sendmail wrapper for php to log calls of the php mail() function.
  Author: Till Brehm, www.ispconfig.org
  (Hopefully) secured by David Goodwin <david @ _palepurple_.co.uk>
*/

$sendmail_bin = '/usr/sbin/sendmail';
$logfile = '/tmp/mail_php.log';

//* Get the email content
$logline = '';
$pointer = fopen('php://stdin', 'r');

while ($line = fgets($pointer)) {
        if(preg_match('/^to:/i', $line) || preg_match('/^from:/i', $line)) {
                $logline .= trim($line).' ';
        }
        $mail .= $line;
}

//* compose the sendmail command
$command = 'echo ' . escapeshellarg($mail) . ' | '.$sendmail_bin.' -t -i';
for ($i = 1; $i < $_SERVER['argc']; $i++) {
        $command .= escapeshellarg($_SERVER['argv'][$i]).' ';
}



//* Write the log
//file_put_contents($logfile, date('Y-m-d H:i:s') . ' ' . $_ENV['PWD'] . ' ' . $logline, FILE_APPEND);

//changed by realtechtalk.com to make the log readable
file_put_contents($logfile, date('Y-m-d H:i:s') . ' ' . $_ENV['PWD'] . ' ' . $logline . PHP_EOL, FILE_APPEND);
//* Execute the command
return shell_exec($command);
?>


Make it executable:

chmod +x /usr/local/bin/phpsendmail

Create Log File (on Centos the log does not get created or written to unless you do it manually)

touch /tmp/mail_php.log; chmod 777 /tmp/mail_php.log;chown apache.apache /tmp/mail_php.log

Step 2 - Backup & Modify php.ini

cp /etc/php.ini /etc/php.ini-bk

(Your php.ini may be in a different location depending on your OS/control panel).

Edit  /etc/php.ini

Find the part that starts with "sendmail" and make it like my example below:

sendmail_path = /usr/local/bin/phpsendmail

; For Win32 only.
;sendmail_from = me@example.com

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
;sendmail_path = /usr/sbin/sendmail -t -i
sendmail_path = /usr/local/bin/phpsendmail

Restart httpd:

service httpd restart

After this you should find entries in /tmp/mail_php.log
