    💡 Quick Tips

    SPF
    Always use -all (hard fail) in production. Keep under 10 DNS lookups.
    DMARC
    Start with p=none to monitor, then move to quarantine → reject.
    DKIM
    Your email provider generates the key pair. You only need to publish the public key as a DNS record.
    CAA
    Restrict which CAs can issue certificates for your domain. Add iodef for violation alerts.
    MX
    Lower priority numbers = higher preference. Always have at least 2 MX records for redundancy.
