Add custom email headers

6/27/2022 5:46 am | #1 mlowe4

Hi is there any way to add custom email headers, my hosting provider has changed it’s email service and now the message returns in plain text rather than a styled HTML email, I need to add MIME format and content type headers for the email to display HTML, it’s returning a Content-Type: text/plain; charset=us-ascii
at the moment and I need to add $headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
Thanks

I believe those headers should be set properly by default if you are using the latest version of the extension. If you provide a url and FTP access then I could test and see what is going on.

Did this help? Tips are appreciated...

The headers currently are:

Date: Tue, 28 Jun 2022 19:48:02 +0000
From: support@nexuscst.com
Message-ID: <bMqtcX8e6zZFHMTiU30zVCoUen89ztQyi9jHzEFamQ@sentrydemo.nexuscst.com>
X-Mailer: PHPMailer 6.1.7 (https://github.com/PHPMailer/PHPMailer)
MIME-Version: 1.0
Content-Type: multipart/alternative;
 boundary="b1_bMqtcX8e6zZFHMTiU30zVCoUen89ztQyi9jHzEFamQ"
Content-Transfer-Encoding: 8bit

The MIME-Version is already there. The Content-Type is set to: multipart/alternative

This is the necessary type to allow both html and plain text versions to be sent. The code automatically produces plain text versions of the code for html clients that don't support viewing html, but it should deliver the html version for any email client that supports it.

Email clients that support html will get the header:
Content-Type: text/html; charset=us-ascii

If you want to change the charset, you can do that in the email settings UI from our extension. I've added it for you and you can see the result on line 53:
$Email->CharSet = "ISO-8859-1";

That should create the correct headers for you.

Is this an issue with the email or the client reading it? If you sent the email to me from the server would I see the same problem? What email client are they using?

I’m pretty sure it’s a problem with the email, I use yahoo web mail and tested it using gmail too and it’s the same if you change the email to yours you would get the same email

The script they provided me works, it’s just universal email doesn’t this is the script they gave me

<?php
ini_set( 'display_errors', 1 );
error_reporting( E_ALL );
$from = "support@nexuscst.com";
$to = "psychic_lowe@yahoo.co.uk";
$subject = "Checking PHP mail";

// To send HTML mail, the Content-type header must be set
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

// Create email headers
$headers .= 'From: '.$from."\r\n".
'Reply-To: '.$from."\r\n" .
'X-Mailer: PHP/' . phpversion();

// Compose a simple HTML email message
$message = '<html><body>';
$message .= '<h1 style="color:#f40;">PHP mail test!</h1>';
$message .= '<p style="color:#080;font-size:18px;">Just a HTML test</p>';
$message .= '</body></html>';

if(mail($to,$subject,$message, $headers)) {
echo "Message was sent.";
} else {
echo "Message was not sent.";
}
?>

I was able to reproduce the issue sending to my email address and I discovered you were using an older version of the phpMailer code. I updated to the latest version from Data Bridge and that appears to have fixed the problem.
