When I looked at /var/log/sqpsmtpd/current via the Server Manager panel, I get the same response as via the terminal:
Displaying lines matching: "dkim".
No matching lines displayed.
There's plenty of outgoing mail on this machine as it hosts quite a few busy Mailman lists, so if there was something in the logs, it would show up.
Per your suggestion, I sent an email from the server to my gmail address and sifted through the email header to see if "dkim-signature" was anywhere to be found. Here are the relevant authentication values:
ARC-Authentication-Results: i=1; mx.google.com;
spf=pass (google.com: domain of root@lists.roe3.org designates 216.125.212.237 as permitted sender) smtp.mailfrom=root@lists.roe3.org;
dmarc=pass (p=NONE sp=NONE dis=NONE) header.from=lists.roe3.org
Received-SPF: pass (google.com: domain of root@lists.roe3.org designates 216.125.212.237 as permitted sender) client-ip=216.125.212.237;
Authentication-Results: mx.google.com;
spf=pass (google.com: domain of root@lists.roe3.org designates 216.125.212.237 as permitted sender) smtp.mailfrom=root@lists.roe3.org;
dmarc=pass (p=NONE sp=NONE dis=NONE) header.from=lists.roe3.orgNothing.
Ever more interesting results from the verifier.port25.com mail header (relevant authentication sections below) . . .
Authentication-Results: verifier.port25.com; spf=pass smtp.mailfrom=root@lists.roe3.org;
iprev=pass (matches lists.roe3.org) policy.iprev=216.125.212.237;
dkim=none reason="message not signed"
ARC-Authentication-Results: i=1; mx.google.com;
dkim=pass header.i=@port25.com header.s=verifier201208 header.b=eVuTRfxA;
spf=fail (google.com: domain of auth-results@verifier.port25.com does not designate 216.125.212.237 as permitted sender) smtp.mailfrom=auth-results@verifier.port25.com;
dmarc=pass (p=QUARANTINE sp=QUARANTINE dis=NONE) header.from=port25.com
Authentication-Results: mx.google.com;
dkim=pass header.i=@port25.com header.s=verifier201208 header.b=eVuTRfxA;
spf=fail (google.com: domain of auth-results@verifier.port25.com does not designate 216.125.212.237 as permitted sender) smtp.mailfrom=auth-results@verifier.port25.com;
dmarc=pass (p=QUARANTINE sp=QUARANTINE dis=NONE) header.from=port25.comI wonder if there's an emoticon for "baffled"?
Thanks again for your assistance and suggestions.

qpsmtpd or sqpsmtpd - there is a difference
It does look like it is signing it (or thinks that it is)
Can you send yourself a mail to say a gmail account or elsewhere and check the header?
Or send one to me at gmail via j h crisp
Without spaces & all that jazz....
The port verifier mail should show you the headers it received as well ?
Look for:
Canonicalized Headers
dkim-signature:v=1;'20'a=rsa-sha256;'20'c=relaxed; blah blah
