To avoid munging, MLMs have a double problem: (1) the evaluator must find
an alternative to DMARC for concluding that the message is "not untrusted",
and (2) the MLM must know that this trust has been granted.
If (2) is known for some recipients but not others, the MLM must be able to
make mungi

Indeed, a problem with munging, or with any other workaround that
mailing-list software might do, is that the problem happens at
subscribers' domains, not at the mailing-list domain, and the mailing

"Breaking long-standing practice" is not the fault of the domain owner

Consider the possible causes of DMARC FAIL:

Your expectations are very different from mine.
1) MLMs have a releationship with their subscribers, and could collect data
for conditional munging, if they chose to do so and their software provided
the necessary capability.
