It's not really a James issue at least not in the sense that you're wanting to 
get your email into an inbox rather than a spam folder. Rather it's a DNS 
issue, as with SPF - you just need an appropriate text record. DKIM differs, in 
that it's a two part thing, you need a public key in your DNS, but also James 
must sign the email with the appropriate private key.

If you wanted to check the DMARC of incoming mail, then it would become a James 
issue, but I don't believe it's worth the pain as checking an online blocklist 
is straight forward and adequate on it's own - maybe with a bit of spamassassin 
as backup.

Didn't the write ups you linked originate from my own one? Months/a year ago 
someone from the James community asked me if they could base something on them. 
I said I was entirely happy for that and remain entirely happy if that was done 
and if you want to add a DMARC article based on what's  at dmatthews.org, just 
go ahead.

I should say that my James foo is out of date as after investigating it, I 
decided to stick with exim4 as the devil I know being better than the devil I 
don't. As I've already said though, for SPF and DMARC, it makes no difference 
if your fighting with James/exim4/postfix etc - these are DNS issues rather 
mail exchanger issues.

Incidentally, if anyone can explain to me why DMARC, which seems to just 
duplicate DKIM and SPF, is not a stupid technology, I'd be pleased to read that
