With some trepidation I ask, like what?
I'd add the whole "Sending side workarounds", mostly as-is, but edited as
needed.
If it's anything like telling mailing lists how to rewrite From lines, the
answer is no. That's way out of scope.
Why? I read:
The working group will specify mechanisms for reducing or eliminating
the DMARC's effects on indirect mail flows, including deployed
behaviors of many different intermediaries, such as mailing list
managers, automated mailbox forwarding services, and MTAs that
perform enhanced message handling that results in message
modification. Among the choices for addressing these issues are:
(which can hardly be considered fully completed with just ARC), and:
The working group will document operational practices in terms of
configuration, installation, monitoring, diagnosis and reporting. It
will catalog currently prevailing guidelines as well as developing
advice on practices that are not yet well-established but which are
believed to be appropriate.
Isn't From: rewriting an operational practice? It is not so important to tell
MLMs how to do, since they already seem to do a good job, as it is to tell
ESPs, which, as you say, don't.
PS: 10.5
Eh?
10.5. DMARC Report Format Registry?
Mac OS X 10.5 Leopard?
Magnitude 10.5?
What did you mean?
