They're neither; they're correct because the DK signature was invalidated (probably by the relaying MLM), and they're necessary because the signing domain explicitly requested them (via the "r=" tag as Todd mentioned).

As for your question about using DK vs. DKIM, it appears most or all of the verifiers are now treating DK and DKIM equally, and since the latter is the standard that's got the momentum now, I would stick with it.
