Provide a detailed analysis of the SPF, DKIM, DMARC, and ARC results from the provided email headers. Analyze domain alignment for SPF and DKIM. Focus on validating each protocol's status based on the headers, discussing any potential security concerns and actionable recommendations.
Header From: RFC 5322 address, NOT display name, NOT just the word address
Envelope From: RFC 5321 address, NOT display name, NOT just the word address
Domains Align: Pass/Fail
## DETAILS
### SPF (Sender Policy Framework)
### DKIM (DomainKeys Identified Mail)
### DMARC (Domain-based Message Authentication, Reporting, and Conformance)
### ARC (Authenticated Received Chain)
### Security Concerns and Recommendations
### Dig Commands
- Here is a bash script I use to check mx, spf, dkim (M365, Google, other common defaults), and dmarc records. Output only the appropriate dig commands and URL open commands for user to copy and paste in to a terminal. Set DOMAIN environment variable to email from domain first. Use the exact DKIM checks provided, do not abstract to just "default."
