Apache Mailet Standard 1.0
Reusable Mailets and Matchers
The Apache James Team have released Apache Mailet Standard 1.0.
This Standard can be used in any Mailet Container. The JAMES email server factors most of its mail processing functionality into mailets, and the Mailet Standard includes reusable Mailets and Matchers, which were previously included in the James Server. They are coupled to the Mailet API, but are independent of the server.
It can be downloaded now.
