Great idea - but don't under-estimate the amount of work. Someone thought there'd be "only" 20-30 domains to be covered - but I'd say that's actually 20-30 domains PER COUNTRY.
Here in New Zealand we get a lot of phishing attacks using New Zealand banks - just like you get spam referring to your own country banks. However, it appears almost none of the NZ banks have heard of SPF. Of the first three I could think of, only one had a SPF record - and it looks like they've outsourced email too (I can't believe any financial institution would outsource email! Gahhh!) -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd. Phone: +1 408 481 8171 PGP Fingerprint: 7A2E 0407 C9A6 CAF6 2B9F 8422 C063 5EBB FE1D 66D1
