Hi, the first one is my DKIM key record (domain is and
selector is

I saw gmail completely ignores my adsp policy record, but yahoo doesn't
and so I think it's correct.

But what about my _domainkey IN TXT "t=n;o=-" policy record? Is it
needed for DKIM or only for domainkey? Should I add my selector in this
policy record (---> IN TXT "t=n;o=-")?

Currently if I disable DKIM signing and I send an e-mail to gmail it
doesn't go in the spam folder as it should.
