I don't understand the choice made when writing the point 6. of the policy
discovery mechanism (Dmarcbis :
https://www.ietf.org/archive/id/draft-ietf-dmarc-dmarcbis-28.html#section-4.7 )
```If a retrieved policy record does not contain a valid "p" tag, or
contains an "sp" or "np" tag that is not valid, then:
* If a "rua" tag is present and contains at least one syntactically
valid reporting URI, the Mail Receiver MUST act as if a record
containing "p=none" was retrieved and continue processing;
* Otherwise, the Mail Receiver applies no DMARC processing to this
message.```
According to this text, the record :
'v=DMARC1; p=reject; sp=quarantin;' (an 'e' is missing at 'quarantine') MUST
be interpreted as 'v=DMARC1; p=none;' because the "sp" tag is not valid.
That's not my reading of the text above. The record contains a valid "p" tag,
thereby escaping the first hypothesis of said text.
Best
Ale
