Hi Peter,

It's actually not quite complicated. DMARC comprises SPF and DKIM.
It's more of publish the two records and configure Exim to sign outgoing
mail. It's pretty easy if you have complete control of your DNS servers.

So here are three links that will demystify the whole thing for you:
https://blog.returnpath.com/build-your-dmarc-record-in-15-minutes-v2/
https://port25.com/dkim-wizard/
https://www.itworld.com/article/2773545/enterprise-
software/how-to-deploy-dkim-email-authentication-in-4-steps.html

You can then use http://www.appmaildev.com/ to test your setup.

Head to http://exim4u.org/, grab the tarball and look at the configuration
files. They have pretty good explanation of how to implement DKIM.

Come back with questions in a day or two.
