I didn't have time before the I-D cutoff but have since added a section on mail to the repo pre-01 version. (See [1] section 3.2.) I'd love to add more detail like that and/or more sections for other protocols if folks have data to offer with references. Consistent with other folks' numbers sent to the list yesterday, (though based on a much smaller sat of data I guess;-) my data shows 10.6% use of TLSv1.0 when talking SMTP/IMAP/POP (or HTTP) over TLS to a population of ~200K IP addresses that listen on port 25 (mail servers). What I don't currently have is a rate of change for that figure. I think that rate of change is the important number for figuring out what to do in the next while. E.g. The WG might conclude that if the percentage of TLSv1.0 is moving down nicely, we should be a bit patient. If it's not moving at all, we can probably move now or in 5 years without that being different. If we're not sure, then get more data... Cheers, S.
