What are the best practices for handling email headers in PHP when using SwiftMailer?

When using SwiftMailer in PHP, it is important to handle email headers properly to ensure proper delivery and formatting of emails. To do this, you should use the setFrom(), setTo(), setSubject(), and setBody() methods to set the necessary header information for the email. Additionally, you can use the addPart() method to add HTML content to the email. 

// Create the Transport
$transport = new Swift_SmtpTransport('localhost', 25);

// Create the Mailer using your created Transport
$mailer = new Swift_Mailer($transport);

// Create a message
$message = (new Swift_Message())
    ->setSubject('Your subject')
    ->setFrom(['your@email.com' => 'Your Name'])
    ->setTo(['recipient1@email.com', 'recipient2@email.com'])
    ->setBody('Here is the message body');

// Send the message
$result = $mailer->send($message);
