Hi all this is the PHP im using:

<?php
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['message'];
$formcontent=" From: $name \n Phone: $phone \n Message: $message";
$recipient = "[email protected]";
$subject = "Contact Form";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
echo "Thank You!" . " -" . "<a href='contact.html' style='text-decoration:none;
color:#ff0099;'> Return Home</a>";
?>

Its working perfectly fine but i would like there to be some text sent with this email that says "This is from your website" or something similar to tell the recipient that it isnt spam (my client isn't tech friendly and sees everything plain text as spam). I'm very new to PHP with nearly 0 knowledge and have no idea how to add something like that. I did have a go at making a new variable with the string inside and then include that in the:

mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");

line but with no success. Thanks for taking the time any help would be welcome.
