The goal of this project is to develop a very simple SMTP server that responds to SMTP requests and makes received messages available for query at a later time. All useful features for a SMTP server that can be used in an automated testing suite.
I forked this project and did a lot of work on it at: http://github.com/rjo1970/dumbster Now a multi-threaded, stand-alone executable jar, and extendable. Fairly heavy refactored. Has tests for file attachments, etc. too. If you're on the dumbster project, contact me.
Project seems dead. I created a patch to support more recent versions and multipart messages. Contact me for details
