How to Avoid Spam Filters with PHP mail() Emails OR Ways To Make Your PHP mail() Emails Less Spammy

<?
mail("recipient@recipient.com", "Message", "A simple message.", "From: The Sender <sender@sender.com>");
?>

While this implementation will successfully send an email, the email will probably get caught in the recipient’s spam filter. Fortunately, there are some simple fixes that can help you avoid spam filters.
