Your responses advertise the exact software you run (Server: nginx/1.24.0 (Ubuntu)). It's not a hole by itself, but it hands attackers a shortcut: they can look up known vulnerabilities for that precise version instead of probing blindly.
The DMARC record on perfcopilot.com uses p=none, which only reports spoofing — it doesn't stop it. Forged mail claiming to be from your domain is still delivered.
perfcopilot.com is not protected by DNSSEC. DNSSEC signs your DNS records so resolvers can detect a forged answer — without it, an attacker who can poison DNS could point your domain at their own server without touching anything you control.
perfcopilot.com publishes no CAA records. CAA tells the world which certificate authorities are allowed to issue HTTPS certificates for your domain. Without it, any CA can be persuaded to issue a cert for your domain, which widens the door to mis-issuance.
