Granted, my only point was around message rejection itself with no
consideration for other email authentication context.
For reference, the M3AAWG BCP section 4

Got it, thanks. We are concerned about DKIM-replay attacks, so while I now
better understand where you are coming from, we would continue to mark such
emails as spam and put them in the users' Junk folders.
Our view is that reputable senders should be able to manage their DNS
accurately, understanding that we are all human and everyone makes mistakes now
and then (be kind!). That's why even with a hard SPF fail we mark emails as
Spam instead of discarding them outright.
Thanks again for helping me better understand your approach here,
Mark

Well, if you want to accept the overwhelming amount of DMARC passing mail
signed with DKIM (which these Hotmail messages are, because they are signed
with valid and aligned DKIM)... then you definitely shouldn't be rejecting it
based solely on the SPF result.

Hi Mark,
Perhaps I'm misunderstanding your inference, but are you saying we shouldn't
reject based on a hard fail SPF record?
Thanks,
Mark

This will definitely showcase how many receivers are still rejecting based on
SPF failure by itself.
There's already many threads on Reddit about this from regular consumers
experiencing bounces they don't know what to do with, it's actually quite sad
reading some of them.

Aloha hotmail,
It seems since you recently changed your SPF and switched from ~all to
-all. It would have been great if you didn't remove at the same time
your IPv6 ranges from it.
It seems the include:spf.protection.outlook.com was removed during the
change. You might want to include it back.
We are starting to receive quite a few tickets that our clients suddenly
don't receive some mails from hotmail.com
Best regards,
Laurent
