A simple PHP mailer class and nothing special.
<?php
require_once('path/to/mailer.class.php');
$m = new Mailer(); // instantiate mailer class
$m->setTo('recipient@example.com'); // recipient (optional second parameter: recipient's name)
$m->setFrom('sender@example.com'); // sender address (optional second parameter: sender's name)
$m->setEnvelopeSenderAddress('sender@example.com'); // optional mail flag
$m->setCC('carbon-copy@example.com'); // mail carbon copy (optional)
$m->setBCC('blind-carbon-copy@example.com'); // mail blind carbon copy (optional)
$m->setSubject('Hello'); // subject
$m->setMessage("If you want something done right, do it yourself"); // mail body text
$m->sendMail(); // send it!
