Eventually. Large mail providers including Google and Microsoft are
working on it, and you can see ARC headers on a lot of their mail, but
for reasons I don't entirely understand it is taking a long time for
them to use the ARC results in their mail filtering,

>2) If so, have we implemented it?

Nope. There is ARC code in Mailman 3, but we are still using Mailman
2. I hear there is a migration plan, eventually.

In the meantime we're using a local hack I invented and Henrik implemented
that rewrites From: addresses in a way that makes it obvious who they are,
e.g.

  [e-mail]

turns into

  bob=[e-mail]

We set up temporary forwards so direct replies work.

This is a kludge but for now it's the least bad kludge I'm aware of
and does not depend on recipients to do anything special.

R's,
