Thanks for the reply. If quotes aren't required in MS DNS, and not having them causes my SFP string to be recognized by some SPF validation tests, then I will remove the quotes.
Would you tell me if this SPF string looks correct?
v=spf1 mx ip4:126.96.36.199 a:ns.pixel8.com -all
All the domains on my mail server have their outgoing mail sent through IP address 188.8.131.52 (FQDN ns.pixel8.com). It's the only IP and name that is authorized to send the mail (-all). Does my SPF string need to any more elaborate than that?
SPF has always been a little confusing for me, so any help would be greatly appreciated.
Which DNS software do you recommend since MS is lacking with their product?
