I can see SPF being a big learning curve to the NZ ISP customer base,
once ISP's start enforcing SPF.
We still see lots of email from customers who have an ispa email set as
their email address but are using our email server because they moved
ISP's but didn't want to change email address. I would be surprised if
any ISP's don't see this.
SPF seems like a very good idea, and will work perfectly for personal
domains, but for big ISP's, xtra/clear/ihug etc. It's going to cause a
huge influx of unhappy customers if it ever gets implemented.
