PHP publishes mail headers in mail body

Today I have faced with an issue: PHP inserts mail headers in the body, for example:

Reply-To: test@test.ru
X-Priority: 3 (Normal)
Content-Type: text/plain; charset=windows-1251
X-Mailer: PHP/5.3.8-ZS5.5.0
Message-Id: <20111211211028.A229D8A0075@example.ru>
Date: Mon, 12 Dec 2011 01:10:28 +0400 (MSK)

Solution was found here: http://www.johnconde.net/blog/php-mail-headers-are-displayed-in-email-body/

The problem maybe in dash between Reply and To or in /r, which should be removed. Example of correct working script:

<?php // Set our parameters $to = 'test@example.ru'; $subject = 'This is a sample email'; $message = 'test'; $headers = 'Reply-To: john@fakedomain.net' . "\n"; $headers = 'From: john@fakedomain.net' . "\n"; $headers = 'X-Mailer: PHP/' . phpversion(); // Send the email mail($to, $subject, $message, $headers); ?>
