Below is header to sent to user:

$to="$mail";
$sub="Thank you!";
$headers = "MIME-Version: 1.0
";
$headers .= "Content-type:text/html; charset=iso-8859-1
";
$headers .= 'From: example.com <[e-mail]>' . "
";
$msg="Dear $nme ,<br/> We received a request to recover your password.<br/> Your Password is $pss .";


$response =@mail($to,$sub,$msg,$headers);

Answer 1

$to='[e-mail]';
$subject='Application Form ';
$message='testing';

 $headers  = 'MIME-Version: 1.0' . "
";
 $headers .= 'Content-type: text/html; charset=iso-8859-1' . "
";
 $headers .= 'From: admin <[e-mail]>' . "
";
 if(mail($to,$subject,$message,$headers))
 {
  echo "Mail Successfully Sent..";
  exit;
 }

It works perfectly to me. You can also use SMTP MAIL instead of this.
