I'm trying to send mail from my ubuntu (17.04) server to gmail, hotmail but the email is going to spam folder. I've checked /var/log/mail.log and I found out that there is a warning about opendkim there:
Jul 25 15:12:31 francooro postfix/cleanup[21233]: warning: connect to Milter service inet:localhost:12301: Connection refused
I've tried to disable chroot check, my firewall is disabled, the opendkim service is up, but it's seems it doesn't listen to any port, so I tried adding another port, and the connection is refused for both ports.
My configuration is :

my chroot is on right now, but I tried to disable it, and it didn't help
my permissions on the keys looks like that:
