Are there best practices for handling email headers in PHP to ensure a professional appearance?

When sending emails in PHP, it is important to properly set the email headers to ensure a professional appearance and avoid common issues such as emails being marked as spam. Some best practices include setting the "From" header with a valid email address, using the "Reply-To" header for replies, and including a relevant subject line. 

// Set email headers
$to = "recipient@example.com";
$subject = "Your subject here";
$message = "Your message here";
$headers = "From: Your Name <youremail@example.com>\r\n";
$headers .= "Reply-To: youremail@example.com\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";

// Send email
mail($to, $subject, $message, $headers);
