Andrea has set up Jenkins notifications for the build server again (Thanks), so you may be seeing a bit of clutter in the list right now.
geoserver-master-live-doc is currently constantly rebuilding due to https://issues.jenkins-ci.org/browse/JENKINS-50683 / https://issues.jenkins-ci.org/projects/JENKINS/issues/JENKINS-7643 (I’m not sure why this same bug isn’t affecting the other doc builds)
The only real option here seems to be remove the include region from the polling plugin so that it uses remote polling (see comments on that ticket for details) - I’ve done so, and it seems to have helped.
I’ve disabled the notifications for all the geotools jobs, and the geoserver-live-docs (I’ve just set them to not send notifications for successive failures, to make them easy to re-enable again), so there should be less clutter in the mailing lists going forward.
