Section 2.1
---------------
This section says in part:
"The report may include...
- Sending and receiving domains"
This language is incorrect or misleading because the receiving SMTP domain
is not part of our standard reporting at all, which is intentional.
(However, Yahoo has chosen to use the filename portion of the report name
to indicate the receiving SMTP domain. This behavior is probably worth
mentioning in a later section, since established implementations trump the
prior specification.)
Instead, the report design is intended to indicate the receiving MX
server's organizational domain. Unfortunately, the current design and
practice does not communicate this information with any confidence. We
should address this by adding a field to indicate the MX server's
organizational domain (or a subdomain which encompassess all of the MX
servers included in the report). If MX servers are in different
organizational domains, they should use separate reports.
Amended language for section 2.1:
"The report may include...
- Sending domain and receiving server organizational domain."
Additional language will be needed elsewhere to clarify these points.
Section 6.1
---------------
This section says
"Aggregate report may expose sender and recipient identifiers, specifically
the RFC5322.From addresses."
This seems contradicted by section 6.3, so I think it can be dropped.
XML Definition
--------------------
Consistent with the above comments, and my previous recommendation to
include HELO and Reverse DNS names, the following changes are recommended
to the XML
Report Metadata Type
