The Internet Assigned Numbers Authority (IANA) maintains a registry for “Email Authentication Result Names”. This registry includes codes that indicate the result of email authentication checks, like those performed by DMARC.
What Has IANA Done for DMARC?
IANA has added several entries to the “Email Authentication Result Names” registry for DMARC. Here’s what the entries look like:
- Code: None
- This is an existing code.
- It means no DMARC policy record was published for the aligned identifier, or no aligned identifier could be extracted.
- The status of this code is active.
- Code: Pass
- This is an existing code.
- It means a DMARC policy record was published for the aligned identifier, and at least one of the authentication mechanisms passed.
- The status of this code is active.
- Code: Fail
- This is an existing code.
- It means a DMARC policy record was published for the aligned identifier, and none of the authentication mechanisms passed.
- The status of this code is active.
- Code: Temperror
- This is an existing code.
- It means a temporary error occurred during DMARC evaluation. A later attempt might produce a final result.
- The status of this code is active.
- Code: Permerror
- This is an existing code.
- It means a permanent error occurred during DMARC evaluation, such as encountering a syntactically incorrect DMARC record. A later attempt is unlikely to produce a final result.
- The status of this code is active.
Remember, this is a simplified explanation. In reality, using DMARC involves a lot of complex processes and technologies. But hopefully, this gives you a basic understanding of the IANA considerations for DMARC authentication results.
