I liked the DKIM guide from this site:

I've got DKIM set up for a multi-domain host and it wasn't too tricky.

Had an issue with DNS entries getting stored in URL-encoded format, 
which turned " " to "%20" (or something).  Raised a ticket, they fixed 
that, DKIM seems to be working.


Besides SPF, TLS, IPv6, and DKIM all help deliverability.

I've got DMARC, but it didn't seem as crucial, just preferred.


I've got a message partially composed from yesterday that I'm meaning to 
finish, but I've got to go through several domains' RRs and check that 
they've all got DKIM and DMARC properly configured.

I thought they were, and the OP post had me double check and find some 
missing stuff ("thanks, Rick").



TL;DR - that link makes short work of DKIM with openDKIM.
