im using these headers in my PHP to make sure that emails are avoiding the junk mail folder but they dont seem to be working very well.

PHP Code:
    $headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
     
$headers .= "From: hello@somebodylovesyou.co.uk <hello@somebodylovesyou.co.uk>\r\n";
     
$headers .= "Reply-To: hello@somebodylovesyou.co.uk <hello@somebodylovesyou.co.uk>\r\n";
     
$headers .= "Return-Path: hello@somebodylovesyou.co.uk <hello@somebodylovesyou.co.uk>\r\n";
     
$headers .= "X-Priority: 3\r\n";
     
$headers .= "X-MSMail-Priority: Normal\r\n"
is there anythin from the above code that u would change or remover that might help this work?
