Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Harden

   DMARC policy enforces quarantine or reject

   Observed: The DMARC policy for datamartgh.shop was p=none, which asks receivers to take no action on failing mail.

   Why it matters: An enforcing DMARC policy helps receiving mail systems reject email that falsely claims to come from your domain, a common route for phishing your customers.

   What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.

   59% of Telecommunications & Internet peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.

   On Next.js: Use the next/script component with an appropriate loading strategy.
