I’v updated my checkmk instance from 1.6 to 2.0.
Now I have a strange behavior on sending Bulk Notification E-Mails.
In my notification rule I have changed the From Address to a specific E-Mail Address (mailrelay.de), witch is working. (changed E-Mail Addresses in the post for Privacy reasons…)
cat /var/log/maillog (latest)

But as soon as I activate Bulk Notifications, the From Address header won’t be changed any more.

Is this a Bug? Is there anything I’ve missed on new config options? Has anyone a Idea how to get Bulk Notifications / E-Mails working with a replaced From Header?
Thanks for all answers or suggestions I could try out!
