Sometimes you can get away with only: Content-Type: text/html; charset="ISO-8859-1" Content-Transfer-Encoding: 7bit : What if i don't encode the message i.e (no Content-Transfer-Encoding : specified)? Does it impose some security vulnerabilities? These headers just provide more information to the mail client so that it can properly handle and display the message. Some mail clients may be more error-tolerant than others. But really you don't want your messages to be handled and displayed incorrectly. Just as your PHP code should generate HTML-compliant web pages, your code should also generate correctly format email messages.
