Is there anything that needs to be added or corrected?
RFC 6591 introduces the Auth-Failure: field. It lists five possible values for
this field. RFC 7489 and then dmarc-failure define a sixth possible value,
"dmarc", for this field. However, the IANA page for MARF[*] is missing a
registry for these values. I'd add a new subsection more or less like so:
6.2 Authentication Failure Types
IANA is requested to add a registry with the possible values of the Auth-
Failure field. The initial values for this are as follows:
====================================================================|
| Auth-Failure | | | |
| value | Description | Reference | Status |
|==============|=============================|===========|==========|
| adsp | message did not conform to | RFC 6591 | historic |
| | the ADSP signing practices | | |
|--------------|-----------------------------|-----------|----------|
| bodyhash | Body hash mismatch | RFC 6591 | current |
|--------------|-----------------------------|-----------|----------|
| revoked | The DKIM key was revoked | RFC 6591 | current |
|--------------|-----------------------------|-----------|----------|
| signature | The DKIM signature did not | RFC 6591 | current |
| | verify | | |
|--------------|-----------------------------|-----------|----------|
| spf | SPF result was not "pass" | RFC 6591 | current |
|--------------|-----------------------------|-----------|----------|
| dmarc | some or all of the authenti-| This | current |
| | cation mechanisms failed to | document | |
| | produce aligned identifiers | | |
|==============|=============================|===========|==========|
Note that the DKIM-ADSP-DNS field, described as "Retrieved DKIM ADSP record" is
still marked "current" in this IANA page. Whose task is it to turn it into
historic? Should we do it, while we're at it?
