What e-mail header is needed for a message to be displayed as 'via:'?

Question

I have noticed that some mails come with the from address like :

Adam Mannet via www.findyourfriend.com.

What headers do I need to pass to the native PHP mail() function to accomplish this when sending e-mail?

Answer 1

I think the via tag is added by the mail server when somebody uses an external (from his domain) smtp server. Per example, my email is iceduck@iceduck.net but I send email via Gmail's smtp, you will see From iceduck@iceduck.net via Gmail.com. If you want to make the via appear then you'll have to send your mail through the smtp server you want to appear in the via.

I don't think the solution is in the header.

Answer 2

You should check PHP mail documentation. There is a description how to modify 'From' header. You should use additional_headers to change that header information and include 'friendly name' beside your e-mail address.

<?php
// The message
$message = "Message content";
$headers = 'From: User Name <user@example.com>';

// Send
mail('test@example.com', 'My Subject', $message, $headers);
?>

This should make your from address look like: 'User Name via www.example.com'
