I guess this means that people will no longer be able to successfully use a
@wikimedia.org address in their from: field unless they are WMF employees (or
whatever) and use the Google Apps address via webmail or SMTP-AUTH?
Not that I care, but all such existing users should probably be warned.
This is why Andrew in Office IT sent out emails over the past couple of
weeks regarding mail client setup. I don't think he's heard from anyone
who for whom this is an issue, but he's on board for helping people adjust
their outbound mailserver if we can find anyone who needs to.
I was under
the impression that ~all softfail is not an assertion that
something is not authorized and the only way to actually assert that is
with -all hardfail.
