I'm pretty sure DKIM wouldn't include the non-standard threading headers.
/Default/ DKIM configurations probably don't include the threading header(s) (References & In-Reply-To). But it's certainly possible that they are included.
That being said, I see that both References: and In-Reply-To: are included in the DKIM-Signature: of the message that I'm replying to.
I've re-wrapped it to make it easier to read. DKIM-Signature: v=1; a=rsa-sha256; bh=2HJH0z8OPqiZSksYlT5t9QkCZyw3VikRfFdD5Blq7oU=; c=relaxed/relaxed; d=earthlink.net; h=from: reply-to: subject: date: to: cc: resent-date: resent-from: resent-to: resent-cc: in-reply-to: references: list-id: list-help: list-unsubscribe: list-subscribe: list-post: list-owner: list-archive; q=dns/txt; s=dk12062016; t=1666103332;x=1666708132; b=QSe+qudK+EvZiTVCfIIyY1ZZVBmtwmw1sEI1OSB0BRPEpgwr/IM41U43QjJNOOmku5a328ciBXHw1g3ncgL69gfnBrkXSAgcxavl6uQL7J2/3AbNe5w0Kj29w7mZpSPa/8YNMp8KkTaGCrN54EUWys2Zglz0a1EocvpRg3JjeJ99l66dKGxj0EJN7G/akyw26EXdjbbTy7OrNvVQn5z1vaFtLFZtsgmAAJRTsHRspoyaSlnAom7R5vBIUrd5ILqHKcrDpWV9KjsYmLl+pRv3dU57RaEt8VGrATwkfAbyJmTnF3uKNuM03K73NQ9ewWjIgkDhep3RRLesdgjPdrb0iA==Including the resent-* headers is interesting to me, seeing as how they aren't included in the message. I don't know if this was an intentional over-sign or over zealous configuration.
