Hi all.  My DNS is, sadly, hosted on Windows NT 4.0 Server.   I'd love 
to get around to changing that but don't have enough time right now.

I tried putting:

mydomain.com   IN TXT "v=spf1 ptr -all"

into my zone file, updated the serial, and restarted the service.   It 
did not squawk, but when I go to the DNSStuff SPF tester, I get back:

Error: I could not get the SPF string [SPF not supported (the 
mydomain.com TXT record does not exist, negative TTL=3108).].

I assume the zone file has a name like mydomain.com.dns

If you edit the NT based zone file directly it needs to look 
something like this for the main domain record

@          0    TXT "v=spf1 ptr -all

and for non mailing devices

zombiepc   0    TXT "v=spf1 -all

The 0 (zero) is not an obvious thing to do

IMHO for NT DNS, generally much easier to use the windows 
interface for the odd change, or make an example record to 
duplicate by hand if a lot of entries are required.
