Hello folks,

In ticket #64 (https://trac.ietf.org/trac/dmarc/ticket/64), it was suggested that a 
Privacy Considerations section may alleviate some concerns about the ownership of the 
data.  I created an initial attempt, and thought to get some feedback.  I didn't think we 
should go too far in depth, or raise corner cases.  Felt like doing so could lead down a 
rabbit hole of trying to cover all cases. This would go within a "Privacy 
Considerations" section.

* Data Contained Within Reports (#64)

Within the reports is contained an aggregated body of anonymized data pertaining
to the sending domain.  The data is meant to aid the report processors
and domain holders in verifying sources of messages pertaining to the
5322.From Domain.


I'd replace all those 5322.From Domain with main DMARC identifier.


The data should not contain any identifying
characteristics about individual senders or receivers.


The aggregated data refers to names and IP addresses of SMTP servers. It cannot be used to identify individual users.


 An entity
sending reports should not be concerned with the data contained as
it should not contain PII (NIST reference for PII definition), such as email 
addresses or
usernames.


I'd substitute /should not/does not/. Even if a server has a unique user, the domain name and the IP address are those of a public entity, not those of a private citizen.

The term Personally Identifiable Information (PII) is US-national. I think just personal information is of broader use. Personal data is also a valid alternative.
