The ESME Mailet is a plugin for theOpen source Mail Server Apache James, which allows users of an ESME infrastructure (both humans and technical systems) to send email messages to an ESME instance using their own identity. Messages sent through the mailet show up as personal messages from these end users, so people following you get them in the respective blogging timeline.

You will find the guide (PDF) and the ESMEMailet.jar file under Attatchments.
