Are there alternative mailers in PHP that can help avoid header compliance issues?

When sending emails in PHP, it is important to ensure that the headers are compliant with email standards to avoid delivery issues. One common issue is headers being incorrectly formatted, which can result in emails being flagged as spam or not being delivered at all. To avoid this, using alternative mailers in PHP such as PHPMailer or Swift Mailer can help ensure that headers are properly formatted and compliant with email standards. 

// Example using PHPMailer to send an email with properly formatted headers
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');
    $mail->Subject = 'Subject of the email';
    $mail->Body = 'This is the body of the email';

    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'your_smtp_username';
    $mail->Password = 'your_smtp_password';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;

    $mail->send();
    echo 'Email sent successfully';
} catch (Exception $e) {
    echo 'Email could not be sent. Mailer Error: ' . $mail->ErrorInfo;
}
