For my Jenkins job I would like to have Jenkins send e-mails under two conditions:
- The build was fine before, but now it fails.
- The build failed before, but now it is fine.
I do not want it to send e-mails for any additional failing builds between (1) and (2).
I would have expected that having the setting "Send e-mail for every unstable build" unchecked would prevent just that, but I receive e-mail for every single failed build.
How can I achieve my desired behavior? Is this a bug in Jenkins (2.121.2) or the Mailer plugin (1.21)?
