As written, setting the caps manually works as expected. I want simply fix it for Leap 42.3 because the changes in the devel project made Cyrus unusable for users of older Leap releases. Either build there should be disabled for older releases or the changes should also work for older releases. The issue was also recognized in other OBS projects relying on that package from server:mail like server:Kolab:Extras. I added all this stuff to this bug because it was the bug mentioned in the package changelog that leads to the issues with openSUSE Leap 42.3. Also the issue with missing priviliges for writing to /run will be the same on Tumbleweed.
