Send email from your domain – without running your own mail server.

Install a plugin like WP Mail SMTP, then use these settings:

SMTP Host:       mail.sixten.dk
SMTP Port:       587
Encryption:      TLS
Authentication:  On
Username:        your-smtp-user@yourdomain.dk
Password:        your-smtp-password

Or add to wp-config.php with a code-based plugin:

define( 'WPMS_ON', true );
define( 'WPMS_SMTP_HOST', 'mail.sixten.dk' );
define( 'WPMS_SMTP_PORT', 587 );
define( 'WPMS_SSL', 'tls' );
define( 'WPMS_SMTP_AUTH', true );
define( 'WPMS_SMTP_USER', 'your-smtp-user@yourdomain.dk' );
define( 'WPMS_SMTP_PASS', 'your-smtp-password' );

Using PHPMailer (recommended):

use PHPMailer\PHPMailer\PHPMailer;

$mail = new PHPMailer(true);
$mail->isSMTP();
$mail->Host       = 'mail.sixten.dk';
$mail->SMTPAuth   = true;
$mail->Username   = 'your-smtp-user@yourdomain.dk';
$mail->Password   = 'your-smtp-password';
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->Port       = 587;

$mail->setFrom('noreply@yourdomain.dk', 'Your Name');
$mail->addAddress('recipient@example.com');
$mail->Subject = 'Test from Sixten Mail';
$mail->Body    = 'It works!';
$mail->send();
