Hi folks.
We have noticed a number of domains in NZ have entered in their NS's domain.co.nz IN TXT "v=spf1 mx -all"
Working through http://spf.pobox.com/wizard.html seems to suggest that "v=spf1 mx -all" means that only the MXs for the hypothetical 'domain.co.nz' are allowed to send email - otherwise it would be "v=spf1 -all" wouldn't it? (Confusingly, there is a real 'domain.co.nz' and it doesn't seem to publish SPF.) -- James Riden / j.riden(a)massey.ac.nz / Systems Security Engineer Information Technology Services, Massey University, NZ.
