score DKIM_ADSP_ALL 3
score DKIM_ADSP_DISCARD 10
score DKIM_ADSP_NXDOMAIN 3
dla atps nie widzę nic ciekawego
ku potomności zostawię linka wyjaśniającego ADSP
https://en.wikipedia.org/wiki/Author_Domain_Signing_Practices
i zdanie:
DKIM, however, deliberately makes no binding between the DNS domain
of the signer and any other identity found in the message.
https://tools.ietf.org/html/draft-kucherawy-dkim-atps-16
by wyjaśniało dlaczego opendkim jest takie ubogie.
