cannot configure DMARC without DKIM
as the title says, the control panel will not let me create a DMARC record when DKIM isn't already configured. i'm setting the receiver policy as none, valid email addresses for aggregate data and forensic data reporting, selecting only 'generate report if spf failed' for forensic reporting options, and DKIM and SPF identifier alignments are both set to relaxed. but whenever i try to save these DMARC settings, the only response i get from ispconfig is 'no active DKIM record'. i should be able to create a dmarc record even without a dkim record and just have it use SPF. even those at dmarc.org say it should be possible: https://dmarc.org/2017/03/can-i-use-dmarc-if-i-have-only-deployed-spf/
