How can I change Return-Path: email@example.com?
I have a huge issue with emails being blacklisted, due to the fact that their return-path is set to firstname.lastname@example.org, so is there anyone who knows how to change that email to use my domain name?
This is one of the errors that I can see in my email headers:
*Received-Spf: neutral (google.com: 188.8.131.52 is neither permitted nor denied by best guess record for domain of email@example.com) client-ip=184.108.40.206; *
Everything is setup correctly in my PHP function for sending an email, where the sender and reply emails are using the correct domain name, but not the return-path email?
$output .= ‘From: ’.$this->headers['from’].’ <’.$this->headers['sender’].’>’.“\r\n”;
$output .= 'Reply-To: ’.$this->headers['from’].’ <’.$this->headers['sender’].’>’.“\r\n”;
$output .= 'Return-Path: ’.$this->headers['from’].’ <’.$this->headers['sender’].’>’.“\r\n”;
I use an Ubuntu 16.04 installation with WordPress and I’ve activated the Postfix package, which is used to send email via a contact form and a simple PHP mail() function.
