Hallo at all, if I enable DKIM, no full DNS-Record is generated. Just something like this: ._domainkey.thischwa.de. 3600 TXT v=DKIM1; t=s; p= I'm running git-stable 3.1. and it is installed on a new VPS. Did I forgot some dependencies? On another VPS (Debian 8.11, ISPConfig 3.1.11) it works as expected. All hints are really helpful. Kind regards Thilo
