Gitlab email notifications stopped working
Summary
Since mid of November 2019 we are not receiving mail notifications. This applies only to @brandeins.de adresses. Maybe there is a reason why we are on some kind of blacklist?
Steps to reproduce
To something in our project and all members with an adress other than @brandeins.de receive notificatins, but all employee woith @brandeins.de adress won't
Example Project
brandeins / kiosk
