I want to improve deliverability for my outgoing emails with DKIM. I've gotten dkim-filter installed for postfix, using this tutorial https://help.ubuntu.com/community/Postfix/DKIM
It seems to be working, my /var/log/mail.log shows it starting:
Aug 10 18:34:13 mail dkim-filter: Sendmail DKIM Filter v2.8.2 starting (args: -x /etc/dkim-filter.conf -u dkim-filter -P /var/run/dkim-filter/dkim-filter.pid -p inet:8891@localhost)
However, no headers are being generated when I send email and I can't figure out why.
Here is my /etc/dkim-filter.conf https://gist.github.com/6dc92c7efc29aa45991f
And here's what I added to the bottom of /etc/postfix/main.cf
# DKIM milter_default_action = accept milter_protocol = 2 smtpd_milters = inet:localhost:8891 non_smtpd_milters = inet:localhost:8891
Any ideas? Thank you!
P.S. I have the DNS entry setup for it as well at feedmailpro.com (may still be propagating), but I assume it isn't even being checked without the headers in outgoing emails. Thanks!
