design: panel-dkim-signing stage 2 - the pages without OpenDKIM

Health: the opendkim process row goes; the Milter sockets card shows the
panel's signer on its two sockets, dkim-signer · applications (sign.sock)
and · notifications (sign-local.sock) - Q3 of the plan; Configuration
says it reloads Postfix. Domain delete: "stop signing mail as the
domain" for the OpenDKIM reload. System log: mail.log is Postfix's log
(OpenDKIM never wrote to it), its sample line goes. Message page: the
sample's OpenDKIM line becomes a qmgr line. Help, sender check: the
From: line is read as a mail program reads it and must be one address;
DMARC holds the signature to it; the sentence the mockup carried twice
is once. Overview: 5 of 5 sockets.
