What are potential pitfalls when using web.de as a mail server for PHP email delivery?

When using web.de as a mail server for PHP email delivery, one potential pitfall is that web.de may have strict email sending policies that could result in emails not being delivered or marked as spam. To avoid this, make sure to properly authenticate your SMTP connection and set the necessary headers to comply with web.de's requirements. 

// Example PHP code snippet to send an email using web.de SMTP server with authentication

$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";

$from = "your_email@web.de";
$password = "your_web.de_password";

$smtp_host = "smtp.web.de";
$smtp_port = 587;

// Create a new PHPMailer instance
$mail = new PHPMailer(true);

// Set SMTP settings
$mail->isSMTP();
$mail->Host = $smtp_host;
$mail->Port = $smtp_port;
$mail->SMTPAuth = true;
$mail->Username = $from;
$mail->Password = $password;

// Set email headers
$mail->setFrom($from);
$mail->addAddress($to);
$mail->Subject = $subject;
$mail->Body = $message;

// Send the email
if($mail->send()) {
    echo "Email sent successfully";
} else {
    echo "Email could not be sent. Mailer Error: " . $mail->ErrorInfo;
}
