spam

I've been getting very annoyed at this as no matter what it seems spam filters are still calling my websites auto responder as spam. I've set all my headers correctly and this is what I have so far! $headers = "From: Name<name@website.com>\r\n" ."Return-Path: Name<name@website.com>\r\n" ."Reply-To: Name<name@website.com>\r\n" ."Message-ID: <". time() .rand(1,1000). "@".$_SERVER['SERVER_NAME'].">\r\n" ."X-Mailer: PHP v".phpversion()."\r\n" ."MIME-Version: 1.0\r\n" ."Content-Type: text/plain; charset=iso-8859-1\r\n"; @mail($_POST['email'], "Subject", "Message", $headers); Please help me on this

By "honeypot", I mean more or less this practice: #Register form <style> .hideme{ display:none; visibility: hidden; } </style> <form action="register.php"> Your email: <input type="text" name="u-email" /> Choose a password: <input type="text" name="passwd" /> <div class="hideme"> Please, leave this field blank: <input type="text" name="email" /> #the comment is for text-browser users </div> <input type="submit" value="Register" autocomplete=off /> </form> //register.php <?php if($_POST['email'] != ''){ die("You spammer!"); } //otherwise, do the form validation and go on. ?> more info here .

I have been trying to get PEAR::mail to successfully deliver emails to hotmail users without being flagged as SPAM and ending up in the junk folder, i have no problems with yahoo/gmail only with hotmail. google suggested that this is a common problem with hotmail and that possible causes can include incorrect reverse DNS for main IP of the server lack of SenderId/SPF records being blacklisted having checked all of the above i can only think of one other reason - incorrectly formatted headers ? to test this theory i set up outlook to send email via the same address that PEAR::mail uses and sent
