SOLVED PHP Mail Not Sending From Hosted Domain But Server Domain

Hi,

I running CENTOS 6.9 x86_64 kvm – server cPanel & WHM 64.0 (build 36) and have a dedicated IP for mydomian.com

I have installed a script called PHPMailer I'm using to to allow visitors to send ecards to their friends. When I test it it goes through but goes to the spambox. Here is Mail Delivery Reports says:

Event: success
Sender User: user
Sender Domain: mydomian.com
Sender: user@server.myserver.com

The X-Mailer: PHPMailer 5.2.23 github.com/PHPMailer/PHPMailer

Then I have Wordpress installed and a newsletter module installed that sends a auto reply after someone subscribes. It doesn't get sent at all. Here is Mail Delivery Reports says for that:

Event: failure
Sender User: user
Sender Domain: mydomian.com
Sender: user@server.myserver.com

Result: ECDHE-RSA-AES256-SHA384:256 CV=yes: SMTP error from remote mail server after end of data: 550 5.7.0 (SNT004-MC1F47) Unfortunately, messages from (11.11.11.111) on behalf of (mydomian.com) could not be delivered due to domain owner policy restrictions.

I'm not sure why this one doesn't get delivered but I think it's because I have dmarc set up.


*****************************************

I also have Magento ecommerce set up. It goes through prefect. Everything passes i.e. spf=pass, dkim=pass, dmarc=pass, Received-SPF: Pass. X-PHP-Originating-Script: 507:Sendmail.php

So I'm very happy about that.

******************************************

When I run a php test script from mydomian.com

PHP:

<?php
    ini_set( 'display_errors', 1 );
    error_reporting( E_ALL );
    $from = "admin@mydomain.com";
    $to = "me@hotmail.com";
    $subject = "PHP Mail Test script";
    $message = "This is a test to check the PHP Mail functionality";
    $headers = "From:" . $from;
    mail($to,$subject,$message, $headers);
    echo "Test email sent";
?>

It doesn't get delivered it's the same as the newsletter reply as above from Wordpress.

I'm trying to get all the emails to go through like Magento. It seems I need toget mydomain.com to send the and not user@server.myserver.com?

How can I fix this?

Thank you

 

I found the problem here: SMTP PHP Mail Not Routed Through Dedicated IP Address

I had to set the return path!
