php form shows error message once I hit Submit

[amyson]

okay I built this php form for a site and it doesn't go through... Instead I'm getting error message...

Warning: mail() [function.mail]: SMTP server response: 553 5.3.0 <[e-mail]>... DISCARD Spam Relay in \HOSTING\DFS\20\5\0\5\2016609505\user\sites\mywebsitename.com\www\email.php on line 15

It's very simple form.

here is the php code.
<?
$msg = "email from contact form1\n";
$msg.= "name:".$POST['name']."\n";
$msg.= "phonenumber ".$POST['phonenumber']."\n";
$msg.= "email: ".$POST['email']."\n";
$msg.= "accountnumber: ".$POST['accountnumber']."\n";
$msg.= "comment:" .$_POST['comment']."\n\n";
$to = "[e-mail], [e-mail]";
$subject = "contact form from mysite";
$header .= "Reply-To: Some One <[e-mail]>\r\n";
$header .= "Return-Path: Some One <[e-mail]>\r\n";
$header .= "From: Some One <[e-mail]>\r\n";
$header .= "Organization: My Organization\r\n";
$header .= "Content-Type: text/plain\r\n";
mail("[e-mail]", $to,$subject, $msg, $headers); ?>

The last line is line 15 and I think something's wrong with that. I added $header lines after reading some article on line http://www.transio.com/content/how-pass-spam-filters-php-mail

PLEASE HELP. I'm very new to the PHP and MY HEAD IS ABOUT TO EXPLODE

[mail() should have mail(TO, SUBJECT, MESSAGE, HEADERS)

[anoopmail]

This message normally pops up when fake From address specified. try giving any valid email id such as [e-mail]
