Sponsor-Board.de - opendkim error

Hallo zusammen,

ich habe ein Server Upgrade von Jessie auf Stretch gemacht. Soweit läuft alles bis auf opendkim. Bei dem Update kommt folgende Meldung:

Code:

Setting up opendkim (2.11.0~alpha-10+deb9u1) ...

Job for opendkim.service failed because the control process exited with error code.

See "systemctl status opendkim.service" and "journalctl -xe" for details.

invoke-rc.d: initscript opendkim, action "start" failed.
