SPF, DKIM, DMARC #email

By following these two guides: "Getting DKIM, DMARC and SPF to work with Postfix, OpenDKIM and OpenDMARC" and "How to eliminate spam and protect your name with DMARC" - I have installed and configured opendkim and opendmarc on my server, configured them (and Postfix) and added the accompanying DNS records, so now emails from koldfront.dk and asjo.org get signed wit DKIM and I have set up DMARC records for the domains. (I had SPF-records set up a long ago already.)

Yay!

Next year I'll get around to DNSSEC, I'm sure.

Update: if you have people with email adresses on your domain who use Gmail, they need to configure Gmail to use your smtp-server, and in /etc/opendmarc.conf this option is needed: IgnoreAuthenticatedClients true. Seems to work.
