Re: Gmail/email & PHP

all i want to do is send (& receive - using a different address) emails via PHP

The latest error i'm getting is:- Mailer Error: SMTP Error: Could not
authenticate.

<?php

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;


require '/home/users/web/b2978/pow.kwisternet/usr/phpmailer/PHPMailer-master/src/Exception.php';
require '/home/users/web/b2978/pow.kwisternet/usr/phpmailer/PHPMailer-master/src/PHPMailer.php';
require '/home/users/web/b2978/pow.kwisternet/usr/phpmailer/PHPMailer-master/src/SMTP.php';

$mail = new PHPMailer(true);
try {
    $mail->isSMTP();
    $mail->Host = 'smtp.kwister.com';
    $mail->SMTPAuth = true;
    $mail->Username = '[email protected]';
    $mail->Password = 'PASSWRD';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;
$mail->SMTPOptions = [
    'ssl' => [
        'verify_peer'       => false,
        'verify_peer_name'  => false,
        'allow_self_signed' => true,
    ],
];


    $mail->setFrom('[email protected]', 'Kwister Mailer');
     $mail->addAddress('[email protected]');
    $mail->Subject = 'PHPMailer Test mailer';
    $mail->Body = 'This is a PHPMailer test email.';

    $mail->send();
    echo 'Message sent';
} catch (Exception $e) {
    echo "Mailer Error: {$mail->ErrorInfo}";
}


?>
