DKIM DNS policy records

linuxsystems.it._domainkey IN TXT "v=DKIM1; g=*; k=rsa; p=<> ; -----
DKIM linuxsystems.it for linuxsystems.it

_domainkey IN TXT "t=n;o=-"

_adsp._domainkey.linuxsystems.it IN TXT "dkim=discardable"


Hi, the first one is my DKIM key record (domain is linuxsystems.it and
selector is linuxsystems.it).

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 (---> _domainkey.linuxsystems.it 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.

Thanks,
Niccolò
