The signer in the panel's milter with go-msgauth/dkim v0.7.0 (sign.go
read: streaming NewSigner, HeaderKeys over-signing, last-first picking),
relaxed/simple, OpenDKIM's dkim_should_signhdrs[] plus From, the key by
the login's domain and by the server's name for local mail, strict. From
Postfix 3.10.13 milter8.c: multi-line headers come \n-separated, so the
signer rebuilds them with CRLF. disable_mime_output_conversion=yes, unset
until now. The oracle dkimpy (python3-dkim 1.1.8-2 in trixie). Three
stages, 2.8.0. Open for the owner: where the signer runs, the key
directory's name, Health's label.
