How can the error "MAIL FROM command failed" be resolved when using PHPMailer?

The error "MAIL FROM command failed" typically occurs when the email address specified in the `setFrom` method of PHPMailer is invalid or not accepted by the SMTP server. To resolve this issue, ensure that the email address provided is correctly formatted and authorized to send emails through the SMTP server. 

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

$mail = new PHPMailer(true);

try {
    $mail->setFrom('your_email@example.com', 'Your Name');
    // Add more code to set other email parameters and send the email
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
