@_voidzero@UK_Daniel_Card Are you sure? ~all is a soft fail so valid IPs will still PASS and DKIM check will not interfere whatever the results.
If you want to force a DKIM chech then the only way seems to be to not set SPF.
This is the issue with the current DMARC way of checking based on SPF or DKIM
Most DNS traffic is still not cryptographically validated.
With the publication of National Institute of Standards and Technology’s updated Secure Domain Name System (DNS) Deployment Guide (SP 800-81 Rev. 3), it’s a good time to reassess DNSSEC.
And don't forget your MX domain(s) so if you (still) use M365 Exchange Online with the legacy https://t.co/YXo6Pgaa92 domain, time to switch to the newer DNSSEC protected one: https://t.co/3xMeejW0o0.
Folks, this sort of thing doesn't happen every day.
I promise, this is going to be a huuuge event for everyone in cybersecurity.
So, sign up, buckle up and enjoy the ride!
