A plain-language guide explaining SPF, DKIM, and DMARC email authentication standards and how they protect domains from spoofing and phishing. It is a documentation/tutorial repository rather than runnable software.
Use cases
- understand how SPF DKIM and DMARC work
- fix emails going to spam folder
- set up email authentication for my domain
- learn why transactional emails fail DMARC
- prevent domain spoofing and phishing
- explain email security to my team
- check my domain's SPF DKIM DMARC status
When to choose
- you need a beginner-friendly explanation of email authentication
- you send transactional emails and want them to reach the inbox
- you're configuring DNS records for SPF, DKIM, or DMARC and want context
When to avoid
- you need a tool or library to generate or validate DNS records
- you want automated DMARC report analysis
- you need an implementation, not an explanation
