Email2HTTP is a new service that aims to make it easy to handle incoming email in web applications by writing simple PHP scripts.

Email2HTTP handles all the email for your domain, and forwards emails which match your filters to a URL of your choice, by HTTP POST

For example, after you link an email domain to a URL you can handle email by simply:

<?php
$name = $_POST["body"];
$description = $_POST["subject"];
$photos = $_FILES;

// do something with the data
saveToMyDatabase($name, $description, $photos);
?>
