// Tell PHPMailer to use SMTP

$mail->isSMTP();

// Configure the SMTP server details

$mail->Host = 'smtp.example.com';

$mail->SMTPAuth = true;

$mail->Username = 'yourusername';

$mail->Password = 'yourpassword';

$mail->SMTPSecure = 'tls';

$mail->Port = 587;

// Set the email details

$mail->setFrom('your@email.com', 'Your Name');

$mail->addAddress('recipient@email.com', 'Recipient Name');

$mail->Subject = 'Email Subject';

$mail->Body = 'Email message body';

// Send the email

if (!$mail->send()) {

echo 'Message could not be sent.');

echo 'Mailer Error: ' . $mail->ErrorInfo;

} else {

echo 'Message has been sent.';

}

By using an SMTP server with PHPMailer or SwiftMailer, you can take control of your email delivery and ensure that your messages are delivered reliably and securely.
