Actually the integration will be dropped since in favor of a pop box fetcher. BTW if anyone wants to work on this it's not hard to do
Send me some information about what you are thinking about for a "pop box fetcher" and I can look into it.
A simple jboss service that start/stop a timer based task.
This task fetch mails in a box through pop protocol with javamail.
Then it insert post in Nukes, it works already for jbossmail :
You have to adapt the code to work with pop/javamail rather than jbossmail
