[SOLVED] sending email that will not be filtered as junk

[jas4]

I'm wanting to write a piece of code that will send an email to a number of different email address's  after getting the email address's out of an mysql query.

 

I'm using a while loop to get around every email address, and I want the email address to have html in it.

 

the script I wrote works only for some email address's, for email address's like hotmail and outlook express it gets filtered out by the junk filter. This is the code I've got just now:

 

  
  while ($row = mysql_fetch_array($getEmail)){
  $email =  $row['memail'];
  $rand = check_input(random_string('alnum',32));//the random key for every invite
  $inviteid = "inv".rand(1,100000000000000000);
  echo $email."<br>";
  $to = $email;
  $from = 'myaddress@mydomain.com';
  $subject = 'invite';
  $message = "<a href='http://www.mysite.com>Click Here</a>";



//$headers = "From: " . $from . "\r\n";

$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
$headers .= "Content-Transfer-Encoding: 7bit\r\n";
$headers .= "From: " . $from . "\r\n";
$mailsent = mail($to, $subject, $message, $headers);
}

 

any suggestions for getting through the junk email filters?

 

thanks

It helps if you use more arguments in mail();

mail($to, $subject, $message, $headers, '-f'.$from);
