Sorry for the noise. I'm just confirming that From-munging still happens
on IETF mailing lists (see

From protonmail, this is an unsigned message.
My understanding has always been that the munging happens if the original
Author Domain has published a DMARC policy that isn't p=none, like
protonmail.com has done:
$ dig +short _dmarc.protonmail.com txt
"v=DMARC1; p=quarantine; fo=1; aspf=s; adkim=s;"
