Why the VestaCP installation does not prepare correct SOA, DMARC, DKIM records?
For SOA, I have to do → https://blog.tomlot.eu/vestacp-b%C5%82% ... rekord-soa. In the case of DMARC or DKIM records, the mail does not arrive or it goes to spam. (IP is not on DNSBL)

The DNS (which also becomes SOA) if properly configured in the VestaCP user and then in DNS. The rDNS is something you should do with your server and DMARC provider that I remember as DKIM is also your choice to put it.
