Are there any best practices for handling email sending errors in PHP applications?

When sending emails in PHP applications, it is important to handle any potential errors that may occur during the sending process. One common approach is to use try-catch blocks to catch any exceptions that may be thrown when sending an email. This allows you to gracefully handle the error and provide feedback to the user or log the error for further investigation. 

try {
    // Code to send email
    // Example: mail($to, $subject, $message);
} catch (Exception $e) {
    // Handle the error, e.g. log the error or display a message to the user
    echo 'An error occurred while sending the email: ' . $e->getMessage();
}
