1) Sample PHP Form Code: 

<form action="phpsend.php" method="post">
Your Name:<input type="text" name="name" />

E-mail:<input type="text" name="emai" />
<input type="submit" value="Submit">
</form> 

2) Create a file called phphsend.php with following code (modifying with your address):

PHP Code:

<?php
//Declare the variables of your form

$recipient = "USER@YOUR-DOMAIN-HERE.COM";
$subject = "Testing.. 1 2 3";
$message = "Hi there!";
$from = "PHP mailer test";

//Contents of form
$name= $_POST['name'];
$email = $_POST['email'];

//mail() function sends the mail

mail($recipient,$subject,$message,$from," -f [email]VALID-USER@THISDOMAIN.COM[/email]);

?>
