What is the correct syntax for SPF records on dynv6?

As per the title…is it:

  1. ““v=spf1 redirect=icloud.com””
  2. “v=spf1 redirect=icloud.com
  3. v=spf1 redirect=icloud.com

I read somewhere that it depends 100% on the input processing… I tried the double quotes so far but the online SFP checkers can’t find anything…of course it hasn’t been 72 hours yet…

Any help is appreciated. Thanks.
