PHPMailer V6 with PHPList V3.3.3?

Has anyone configured PHPMailer V6 with PHPList V3.3.3?

I’m interested in that too… PHPMailer 5.2 is no longer being supported for feature updates, and will only be receiving security updates from now on… Using PHPMailer 6 would be great…

My upgrade to PHPList V3.3.3 has resulted in one of my accounts being unable to send any mail, and I cannot find anything wrong with the setup. I’m probably going to do the PHPMailer upgrade just to see if that’s a problem.

Anyone to help updating PHPMailer to 6.0 ?? I found that there is a bug in PHPMailer 5.2.2 related to DKIM signature : It does not work correctly. The solution seems to use PHPMailer 6.0 (I think because all the DKIM part has been modified). How can we use PHPMailer 6.0 ?

EDIT. I tried to upload PHPMailer 6 files to the /admin/PHPMailer6/src directory and modify the file /admin/class.phplistmailer.php replacing

if (defined('PHPMAILER_PATH') and PHPMAILER_PATH != '') {
    //require_once '/usr/share/php/libphp-phpmailer/class.phpmailer.php'
    require_once PHPMAILER_PATH;
} else {
    require_once dirname(__FILE__).'/PHPMailer/PHPMailerAutoload.php';

by the following :

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
require_once dirname(__FILE__).'/PHPMailer6/src/PHPMailer.php';
require_once dirname(__FILE__).'/PHPMailer6/src/SMTP.php';
require_once dirname(__FILE__).'/PHPMailer6/src/Exception.php';

but it does not work…

Please help updating to PHPMailer 6…
