How can the MIME-Type be utilized in PHP to improve the delivery success rate of emails sent using the mail() function?

When sending emails using the mail() function in PHP, specifying the MIME-Type can help improve the delivery success rate by ensuring that the email content is correctly interpreted by the recipient's email client. This is particularly important when sending HTML emails or emails with attachments. 

// Set the MIME-Type for HTML emails
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

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