This gives the information needed to evaluators to undo the fromMunging on
their end.
Well, call me a pessimist if you will, but I parse this as: generalize
FromMunging now in the hope for a future, "potential", solution. It
looks like a trap: if FromMunging gets even more normalized, evaluators
will have even less incentive to work towards an actual fix.
The best outcome I see is that power users will be able to undo the
munging client-side with a MUA-plugin. Which is nice, but only solves
the problem for a very small part of the community.
Restoring the original From: is already possible. The filter I use does it on
about 50% of cases, because it tries to verify the original signature, which
not always succeeds. If, instead of a generic approach, one authenticates this
list's messages by IP, mail.ietf.org [50.223.129.194], it can then just replace
X-Original-From:. Different lists save the original From: in different places.
If FromMunging were more normalized, it'd be easier.
Best
Ale
