I have used sparkpost email for my website http://hlwmm.org. I have used php Phpmailer library with Sparkpost SMTP. It was working fine but its not working now. Below is my code
// Import PHPMailer classes into the global namespace
// These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
//Load Composer's autoloader
require 'vendor/autoload.php';
$mail = new PHPMailer;
$mail->SMTPDebug = 2;
$mail->isSMTP();
$mail->Host = 'smtp.sparkpostmail.com';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = 'SMTP_Injection';
$mail->Password = 'XXXXXXXXXXXXXXXXXXXXXXXX';
$mail->setFrom('inquiry@hlwmm.org');
$mail->addAddress($to);
$mail->Subject = "Test Subject";
$mail->Body = "Test Sparkpost Email";
$mail->send();
I am getting below error
