Hi, I had still this old op= modifier "draft" 03 in the form
of a possible SPF chapter 6.3 in my "draft collection".
Now I've removed the op=nosub stuff (without zone cut it will
be pointless), and I've transformed the rests to a proper XML
input for xml2rfc at <http://xml.resource.org/>.
While I was at it I've completely rewritten the op=helo and
op=trusted parts (original ideas posted here by Hector and
Meng some months ago). op=auth is was it always way, dubious.
Finally I've added a new op=nohelo, an option for FQDNs which
are never used as "HELO" identity. For the complete result see
<http://purl.net/xyzzy/home/test/draft-spf-6-3-options-04.txt>
Comments welcome, no comments are also fine, the text has a
built-in "SPF Council lock". Bye, Frank
