We have noticed a number of domains in NZ have entered in their NS's domain.co.nz IN TXT "v=spf1 mx -all"
This means domain.co.nz will never attempt to send emails at all. (but valid emails are trying to be sent). I've talked to a couple of domain holders who had this and they've fixed them but most said it was done ages ago and they where playing and never expected it to catch on (but it has a lot looking at the number)
Hi Craig, I'm not certain that's quite right I've been experimenting with it too and the spf wizard (at spf.pobox.com) says of domain.co.nz, which is incidentally real: v=spf1 This identifies the TXT record as an SPF string. mx This wizard found 2 names for the MX servers for domain.co.nz: domain.co.nz and mx2.cedant.com. (A single machine may go by more than one hostname. All of them are shown.) The servers behind those names are allowed to send mail from domain.co.nz. -all No other servers are allowed to send mail from domain.co.nz. This is a good default. This seems to me to be a quite possible situation? Happy to be corrected, I'm certainly no expert on this. Cheers Bob -- Robert Gray bob(a)brockhurst.co.nz
