mailing form send the mail to junk..code inside

Hello,
I use a wordpress theme that has a mailing form, but when users send me email it goes to the HOTMAIL junk mail, here is the code for the php file..

  <?php
  		if(isset($_POST['submit'])) {
          error_reporting(E_NOTICE);
          function valid_email($str)
          {
          return ( ! preg_match("/^([a-z0-9\+_\-]+)(\.[a-z0-9\+_\-]+)*@([a-z0-9\-]+\.)+[a-z]{2,6}$/ix", $str)) ? FALSE : TRUE;
		     }
          if($_POST['name']!='' && $_POST['email']!='' && valid_email($_POST['email'])==TRUE && strlen($_POST['comment'])>1)
          {
              $to = preg_replace("([\r\n])", "", hexstr($_POST['receiver']));
			  $from = preg_replace("([\r\n])", "", $_POST['email']);
			  $subject = "Website contact message from ".$_POST['name'];
              $message = $_POST['comment'];
			  
			  $match = "/(bcc:|cc:|content\-type:)/i";
				if (preg_match($match, $to) ||
					preg_match($match, $from) ||
					preg_match($match, $message)) {
				  die("Header injection detected.");
				}
              $headers = "From: ".$from."\r\n";
   			  $headers .= "Reply-to: ".$from."\r\n";
             
        if(mail($to, $subject, $message, $headers))
              {
                  echo 1; //SUCCESS
              }
              else {
                  echo 2; //FAILURE - server failure
              }
          }
          else {
       	  echo 3; //FAILURE - not valid email

          }
		  }else{
			 die("Direct access not allowed!");
		   }
		   
		    function hexstr($hexstr) {
				  $hexstr = str_replace(' ', '', $hexstr);
				  $hexstr = str_replace('\x', '', $hexstr);
				  $retstr = pack('H*', $hexstr);
				  return $retstr;
				}

      ?>

PHP:

Thanks.

 

Keep the 'From' header to be an email address on your website (See why is my php script not sending emails ) Also, try adding these headers: Date, Return-Path

 

Set hotmail to not 'junk' email from your site.

 

Perhaps your IP has been black listed or the content in the email is being detected as spam.

 

My email id has been marked spam by few servers, can anyone tell me who are the email spam list service provider for Google, Yahoo & Rediff?? mail me on

 

Technically, Hotmail is responsible for this, as they are the one handling incoming emails and marking them as spam.

 

Send emails using SMTP, this way you are sure that your email will not be marked as spam almost all the times.
