This MAY be used. If this is acceptable, I'm happy. Unfortunately, I wouldn't have thought this solution would have been acceptable after reading the statement of the original posting, and as long as the IESG doesn't indicate that it is acceptable, I'll continue to be uncertain. So as far as I can tell, the essence of my original response remains: The original posting would have benefited greatly by including a bit of rationale and examples; and my suggestion would be to do any needed revision to the older statement: http://www.ietf.org/IESG/STATEMENTS/mail-submit-policy.txt and issue a new version of that, which seems to give the background, rationale and examples missing from the latest statement. If the latest statement is going to be allowed to stand, at least I am going to feel that I'm guessing far more than I'm comfortable with regarding exactly where the line between acceptable and non-acceptable technical solutions to spam filtering goes. If the IESG finds itself unable to find the time needed to revise the older document I'm also offering to provide revised text based on that document, in the interest of having policy I feel can be read, understood and followed without too much ambiguity.
