Subject: Re: [ietf-dkim] Proposal: Removal of AUID (i= tag/value)
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.
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
So for the 3.5M signatures we've seen, compare each of them to all of the other
ones to see if one is X.<domain> while the other is just <domain>?
I'll see what I can come up with.
NOTE WELL: This list operates according to
