I produced a php mail function in wordpress custom page and also the php mail function work nicely. But, after i get the email from that wordpress custom page, My email mailbox say showing my hosting user title and hostuser@lome.dreamhost in email mind section. So, can there be in whatever way to get rid of the consumer title and hosting site address? Things I make use of the code in wordpress custom page are below,

 <?php
    if (isset($_REQUEST['email'])) {

$admin_mail = get_bloginfo('admin_email');

$header  .= 'MIME-Version: 1.0' . "\r\n";

$header .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

$header .= "Email From " . $_REQUEST['email'];

$subject = "Testing Form" ;

$message .= 'Testing Form For Removing user name ';

$message .= "email request and other Request are here";

mail( $admin_mail, "Subject: $subject",$message, $header );

} else {
    Here is form<form>
}
?>

this isn't a legitimate mail header

$header .= "Email From " . $_REQUEST['email'];

try:

$headers = 'From: webmaster@example.com' . "\r\n" .
    'Reply-To: webmaster@example.com' . "\r\n" ;
