On postfix how do I override the mydomain value in PHP

  • 772

In my postfix log I have the following when I send e-mail from a PHP based web site:

Feb 11 11:52:04 cp5 postfix/qmgr[6007]: 93C6E79C4D1: from=|[email protected]|, size=3266, nrcpt=1 (queue active)

(I substituted | for smaller-than / greater-than signs.)

The problem with the above is that I need to control the "FROM:" address. I know I can control the "@domain.com" address by modifying the "mydomain" in Postfix main.cf file and I had to do that in order to stop e-mail from bouncing in the first place. The problems is now people are reply to "[email protected]" and I don't want that.

This is a Plesk 9.5 server which as far as I know runs a stock standard Postfix installation. I would like advice on how to fix this problem in my PHP script.

  1. This is something you can do from your PHP script:

    Have a look at Examaple #2 here:

    $to      = '[email protected]';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: [email protected]' . "\r\n" .
    'Reply-To: [email protected]' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

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

    This example also gives you control over the Reply-To headers. There's no need to touch anything in Postfix!

  2. Use -f option(sender address):

    <?php
mail('[email protected]', 'the subject', 'the message', null,
   '[email protected]');
?>
