There are cases in build setup where you want to have "notify people who broke the build" or equivalent selected, but certain people (or internal system committer users/etc.) should not be notified just because a developer broke the build.
In my case, it's cause we have a separate repository with CI utility scripts that is included in the checkouts. As it stands now, if a dev on the main project repo breaks something - any committer on the CI tools repo ALSO gets notifications of those failing builds in the mean time. Granted - they could be a build breaker, but in our environment, that's the .1% case.
Exclude Recipients: [ ] - takes a comma separated list of email addresses
Exclude Patterns: [ multiline ] - takes a newline separated list of regexes or email addresses
Note - I've listed both mailer-plugin and ext-mail-plugin as they both have this functionality, but I expect that this issue will need to be split/cloned.
