一覽

SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication Reporting and Conformance) are email authentication standards preventing domain spoofing and phishing. SPF authenticates sender IP; DKIM cryptographically signs messages; DMARC enforces policy (reject, quarantine). Essential for email deliverability, compliance (HIPAA, SOX), and brand protection. Learnable in 2–3 weeks. Overlaps with email infrastructure, security operations, and compliance.

什麼是 SPF DKIM DMARC Standards

Email authentication standards prevent domain spoofing, phishing, and email fraud. Three standards work together: 1. SPF (Sender Policy Framework): A DNS TXT record listing authorized mail server IP addresses for your domain. Receivers check SPF to verify the sender's IP is allowed.

❓ 常見問題

What does SPF protect against?
SPF verifies the sender IP address is authorized to send email for your domain. Prevents basic email spoofing but can be bypassed with header rewriting.
Is DKIM encryption?
No. DKIM cryptographically signs message headers to prove they weren't tampered with. Recipients verify signatures using your public DKIM key in DNS.
What's the difference between DMARC reject and quarantine?
Reject: failed DMARC messages are blocked. Quarantine: messages go to spam folder. Start with quarantine to catch false positives.
Can I use SPF, DKIM, and DMARC together?
Yes, all three are complementary. SPF + DKIM + strict DMARC enforcement is modern best practice.
What if I send email from multiple services (e.g., Mailchimp + Sendgrid)?
Each service needs its own DKIM record. SPF includes their IP ranges. DMARC aligns both with your domain.
