| Config | Meaning | Risk |
|---|---|---|
| v=spf1 ~all (softfail) | SPF suggests blocking but doesnt enforce | Spoofed emails may pass |
| v=spf1 ?all (neutral) | SPF does nothing | Totally permissive |
| v=spf1 include:amazonses.com ~all | SES can send as domain | Any AWS SES account can spoof |
| v=DMARC1; p=none | DMARC disabled | Zero spoofing protection |
| v=DMARC1; p=quarantine | Failed emails go to spam | Partial protection |
| v=DMARC1; p=reject | Failed emails rejected | Full protection |
| DKIM missing | No cryptographic signature | Email can be forged |

With v=spf1 include:amazonses.com ~all:
Real-world case (CRITICAL): Political party -- DMARC p=none on both domains (party.org.br, party.com). SPF with include:amazonses.com (any SES account can send as the domain). Total email spoofing.
| Issue | Solution |
|---|---|
| SPF lookup limit | DNS has 10 lookup limit for SPF includes |
| DKIM selector unknown | Try common selectors: google, selector1, selector2, 2022, 2023 |
| DMARC reporting | rua=mailto: may leak authentication results to third party |
# Verify email spoofing is possible
# Send test email and check headers:
dig +short TXT _dmarc.target.com
# If p=none -> confirmed spoofable
