Starter checklist
Confirm SPF records are configured correctly, end with strict '-all' enforcement, and authorize only approved servers. Deploy 2048-bit DKIM keys across all corporate, marketing, and third-party mail engines and verify alignment. Establish a DMARC policy of 'reject' or 'quarantine', actively configuring reporting streams for spoofing monitoring. Audit MX and DNS record entries to ensure no dangling subdomains exist that could allow routing takeover. Preemptively register and monitor lookalike business domains to block incoming impersonation attempts. Enforce Google Workspace or Microsoft 365 security baseline logs audits for suspicious API/third-party access.Secure before they strike
