DKIM on postfix relay server

dkim postfix smtp amavis

I have resolved this question with OpenDKIM by using SigningTable, KeyTable and TrustedHost parameters.

  • /etc/opendkim/KeyTable – a list of keys available for signing
  • /etc/opendkim/SigningTable - a list of domains and accounts allowed to sign
  • /etc/opendkim/TrustedHosts – a list of servers to trust when signing or verifying

The guide I used can be found on this blog
