Ecco il codice completo che ho riscritto ed ora è senza errore 500
Codice PHP:
use \PHPMailer\PHPMailer;
use \PHPMailer\SMTP;
use \PHPMailer\Exception; $path=dirname(dirname(__FILE__));
require $path.'/librerie/PHPMailer/PHPMailer.php';
require $path.'/librerie/PHPMailer/SMTP.php';
require $path.'/librerie/PHPMailer/Exception.php'; // Instantiation and passing `true` enables exceptions
$mail = new PHPMailer(true);try {
//Server settings
$mail->SMTPDebug = 2; // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'smtp.office365.com'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = email@email.it; // SMTP username
$mail->Password = 'password'; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587; // TCP port to connect to //Recipients
$mail->setFrom('email@email.it', 'Mailer');
$mail->addAddress('email@tiscali.it', 'Luca Valentino'); // Add a recipient
$mail->addReplyTo('mail@tiscali.it', 'Luca Valentino');
// Content
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients'; $mail->send();
echo 'Message has been sent';
} catch (Exception $e) {
echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
