HTML fill-in and submit form

If you wanted to do it in PHP you can use the built in Mail() function.

You need to configure the settings for Mail in php.ini - instructions here.

Quick example PHP/HTML code (should work but I haven't tested it). Sorry the form is ugly. I couldn't be arsed to format it properly.

<?php
	if (!$_POST['submit'])
		{
			?>		
			<form action="<?php echo $_SERVER['PHP_SELF']?>" method="post">
				Address: <input type="text" name="address" size="50"><br>
				Subject: <input type="text" name="subject" size="50"><br>
				Message: <input type="text" name="message" size="50"><br>
				<input type="submit" name="submit" value="Send">
			</form>
			<?php
		} else {
			$addr = $_POST['address'];
			$subj = $_POST['subject'];
			$msg = $_POST['message'];
			$result = mail($addr, $subj, $msg);
			if ($result)
				{
					echo "Mail sent!";
				} else {
					echo "Unable to send!";
				}
		}
?>

[edit] Just tested it and it works fine.
