Are there any specific PHP libraries or methods recommended for sending emails with correct headers to avoid being marked as spam?

When sending emails through PHP, it's important to set the correct headers to avoid being marked as spam. One way to do this is by using the PHPMailer library, which provides a reliable and secure way to send emails with proper headers. By setting the necessary headers such as From, Reply-To, and MIME type, you can improve the deliverability of your emails and reduce the chances of them being flagged as spam. 

<?php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

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

// Set the necessary headers
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your@example.com';
$mail->Password = 'yourpassword';
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->Port = 587;

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

// Send the email
if ($mail->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Error sending email: ' . $mail->ErrorInfo;
}
