Hire someone to check and fix my DMARC

Just bought a site that is 20 yrs old, and currently programmer does not want to fool with virtualmin since he is used to whm… I need help setting up dmarc on my server, dkim and spf seem fine… site was so old, and was not updated in last 2 years dmarc was never setup, if you have experience and a trusted worker on here reach out, can pay by Paypal, an expert can get this done in 10 minutes

Its not that hard, is virtualmin running the DNS and is virtualmin up-todate?
Maybe post your current software versions, copy and paste here with this icon.

How do I see if virtualmin running the DNS? I see it needs tons of updates
