SMTP server (library) for receiving emails, written in pure PHP. This library provides an interface to the SMTP server-side protocol with PHP. It creates a \Zend\Mail\Message Class object for every incoming email and hands this object to a custom PHP function for further processing. The project is in Beta status, so it's not recommended for production use. The d in SMTPd stands for Daemon. This script can run in background like any other daemon processes. It's not meant for running as a webapplication.
