The IRD/SSC/Treasury (the 3 most important NZ government areas) have SPF records (and they use -all which is good).
That is good to hear that it's been implemented there. As I've posted before, some arbitrary digging has shown that the only [major] financial institution in NZ using SPF is american express. Worrying that no local banks have implemented it.
Before you reply. I've heard all the Anti-SPF abuse before. Yes it can break forwarding, but people shouldn't forward without your permission (and then you change your SPF records to allow this)
You can't control what people do on their own platform, and it is certainly well within my rights as a mail recipient to forward email from one mailbox to another. You should not prevent me from doing that, and it would be foolish to say "shouldn't forward without your permission".
