Announcing java.net issue police
One of the common problems of java.net project owners is the e-mails that people send to email@example.com. This list is normally reserved for the automatic notifications from the issue tracker (thus it gets lower level of attention), but mistaken users often think this is the list to report any problems, and send in e-mails directly.
The "issue police" daemon monitors the issues list, and if it finds such an e-mail, it will politely remind the user that the issues list is for notifications only. It's very easy to use, too — just add firstname.lastname@example.org as a subcriber to your issues list.
