I recently came back to work and before I left I had unsubscribed to all categories so I received no mail during my absense.
Now I'm back and I see that I'm still watching Logstash and Tracking Announcements, Kibana, Security Announcements. I've enabled "Mailing list mode" since I want emails instead of visiting https://discuss.elastic.co.
Now it appears that I receive mail from all Categories, e.g. X-Pack, Elasticsearch, Reporting.
Have I configured something wrong or is the "category filtering" not working in "Mailing list mode"?
