This is a work in progress sample application for Sling, initially contributed by Igor Bogomolov who wrote it as part of an internship, and meant to create a useful mail archive server that also serves as a more complex Sling sample.
To run this, install the dom, core and mbox bundles from the http://james.apache.org/mime4j/ project on a trunk Sling launchpad instance, and install the bundles provided by this module. Note the MIME4J-231 issue when building the Mime4J bundles.
Then, start at http://localhost:8080/mailarchiveserver/import.mbox.html to import a few mbox files, you can find some at server/src/test/resources/test-files/mbox/
http://localhost:8080/mailarchiveserver.html is the server's homepage.
To import live mail from a mail server you need a Connector - the SLING-3297 contribution does include one for Exchange, but we haven't included it in this sample so far.
Stats (even more work in progress) are available at http://localhost:8080/content/mailarchiveserver/stats.html
