Hi,
There is a thread about ARC sealing in bind-users[*]. They're applying ARC
signatures, although they run Mailman 2. The last message hypothesizes a user
option like so:
*From munging*:
Set this option to /Disabled/ to receive messages with the original From:
line intact. Keep in mind that disabling this option will fail DMARC, so
keep it enabled unless your MTA either doesn't check DMARC or accepts ARC
overrides.
It doesn't seem difficult to implement. It requires trusting the users,
though. Would Mailman implement something like it? Why? Why not?
Best
Ale
