as you may know, an IETF working group is reviewing the SPF spec.
The evaluation of current deployment is nearly completed, but thus far
only analyzes published SPF records. Please contribute to a better
understanding by completing the survey:
When Alessandro suggested this survey a few days ago, the spfbis group
roundly rejected it for a variety of reasons. See the spfbis archives
if you're interested in details.
Please save your time and everyone else's by *not* responding to his
message, and certainly don't send it anywhere else.
R's,
John
