I'm curious of the reasons too, I see some data points, but cannot
conclude any statistics...
May be from the people who do statistics on DKIM, do you see a fair
percentage of DKIM signed sub-domains?
I'm happy to search our data if you can describe what I'm looking for.
If you're referring to a comparison between "d=" and "i=" values, we
do that already:
http://www.opendkim.org/stats/report.html#i_tag
(The anchor tag in the current report has a typo, so if you go before
the next update, you'll need to search for "i=" yourself.)
If you mean something else, describe for me what you're looking for
and I'll give it a go.
the question is:
What are the domains that use a sub-domain for d= ?
for gTLDs, what are the instances of d= where there are 3 levels in the domain
where the 2nd and 1st level is identical.
eg:
d=mail1.example.com
d=mail2.example.com
d=mail3.example.com
We could infer that example.com use different mail streams as they use
different sub-domains to sign their emails
for ccTLDs, in general you need to go one level deeper
eg:
d=mail1.example.com.au
d=mail2.example.com.au
d=mail3.example.com.au
