Quoting from the e-mail help screen:
If configured, Hudson will send out an e-mail to the specified recipients when a
certain important event occurs.
1. Every failed build triggers a new e-mail.
2. A successful build after a failed (or unstable) build triggers a new
e-mail, indicating that a crisis is over.
3. An unstable build after a successful build triggers a new e-mail,
indicating that there's a regression.
4. Unless configured, every unstable build triggers a new e-mail, indicating
that regression is still there.
For each kind of events, what recipients do you suggest should receive e-mails?
At my work, we usually send the e-mail to the whole engineers, alerting the
situation. That makes sure that people are aware of the problem, which is handy
for example when someone does "commit and leave".
Are you sure you want to limit the e-mails to the people who committed?
