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

Subject: Re: [mailop] hotmail.com SPF forgot IPv6
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
