I crunched all the signed mail I've gotten since the beginning of 2010:
2010:
135 adsp -> dkim=all
5 adsp -> dkim=all;
1 adsp -> dkim=all; t=s
38 adsp -> dkim=discardable
194 adsp -> dkim=unknown
6 adsp -> dkim=unknown;
223 adsp -> noerror
8020 adsp -> none
2011:
59 adsp -> dkim=all
5 adsp -> dkim=all; t=s
11 adsp -> dkim=all;t=s
5 adsp -> dkim=discardable
22 adsp -> dkim=unknown
21 adsp -> noerror
2649 adsp -> none
"noerror" is mostly Yahoo, which has CNAMEs but no ADSP record. All
of the dkim=discardable is Paypal. Nearly all of the dkim=all was small
personal domains; the only large one I saw was paypal-inc.com.
orbitz.com and cert.org publish dkim=unknown
I also got about a dozen SPF and Sender-ID records, likely from
ill-advised wildcards.
So in my limited dataset, ADSP usage is if anything shrinking, with only
Paypal publishing discardable.
hmmmmmmmmmm
John, you do realize its only April? 1/4 of 2011?
According to your stats:
2649*4 = 10,596
There will be an extrapolated increase of 2576 by the end of year.
The more valuable data point of interest is the total unique domains,
not how many messages.
Nonetheless, you are exhibiting a personal community network
statistics and everyone's personal community network patterns are
different.
Microsoft hotmail.com has now started to check for ADSP senders.
Their stats will show a significant increase of senders adding
DKIM+ADSP support to better reach hotmail.com users. Hopefully they
will soon begin to do something you didn't do - Promote DKIM and ADSP.
If you want ADSP to increase, you need to support it, champion it.
Something most creators do - be the #1 User and Champion of their own
work.
Love/hate them, Microsoft is still a market leader. Ignore ADSP at
your own peril.
