What are some common limitations or restrictions when using Sendmail over PHPMailer for sending emails?

One common limitation when using Sendmail over PHPMailer is that Sendmail may be disabled or not properly configured on the server, leading to email delivery failures. To solve this issue, you can use PHPMailer which provides a more reliable and flexible way to send emails, including support for SMTP authentication and encryption. 

// Example PHP code using PHPMailer to send an email
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php'; // Include PHPMailer autoload file

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

try {
    $mail->isSMTP(); // Set mailer to use SMTP
    $mail->Host = 'smtp.example.com'; // Specify main and backup SMTP servers
    $mail->SMTPAuth = true; // Enable SMTP authentication
    $mail->Username = 'your@example.com'; // SMTP username
    $mail->Password = 'yourpassword'; // SMTP password
    $mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 587; // TCP port to connect to

    $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';

    $mail->send(); // Send the email
    echo 'Email has been sent';
} catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}
