That assumes there are lists that don't munge From:. Is that real
today?
I wasn't aware that this munging had become a standard, or even
common. It's a popular solution to DMARC specifically, to be sure.
Anecdotal example, but most lists I've been a part of personally, or
worked with domains that had users on various different lists, almost
all of them used munging for domains with p=reject. Without data from
all lists that exists in totality on the internet it's hard to really
say how common statistically, but my experience has seemed that it is
more common, than uncommon._______________________________________________
