I’ve Ubuntu 16.04 I’m trying to config DKIM for sendmail. Getting this error when email is sending: sm-mta: uBILBoWg019671: Milter (opendkim): error connecting to filter: Connection refused by localhost
I’ve added port 12301 to firewall. Also in /etc/opendkim.conf I’ve added: Socket inet:12301@localhost
And also in /etc/default/opendkim: SOCKET=“inet:12301@localhost”
And in /etc/mail/sendmail.mc at the end: INPUT_MAIL_FILTER(‘opendkim’, ‘S=inet:12301@localhost’)
