DKIM with Zentyal development edition
« on: November 21, 2016, 03:24:44 pm »
I've seen this asked about a few times, but nobody ever answered. I got it working, in IMAP/SMTP, Openchange, and SoGo. Here's how

I followed this guide

Skip the parts of the guide which deal with modifications to /etc/postfix/ Instead, modify /usr/share/zentyal/stubs/mail/

and add these 4 lines to the bottom

milter_protocol = 2
milter_default_action = accept
smtpd_milters = inet:localhost:12301
non_smtpd_milters = inet:localhost:12301

Make sure you set up the txt records in your public DNS record properly, then test using or your favorite DKIM verifier.

That was very helpful,,,,,,,,,,,,, actually, it helped me a lot.

After following the steps and the link provided here, I managed to configure DKIM properly.
In my opinion, DKIM is a basic requirement for Zentyal mail server.

Thank you indeed.

You should never modify /usr/share/zentyal/stubs/mail/ but copy it in /etc/zentyal/stubs/mail, then modify that file.

Read the documentation.
