John,

I am confused. I got these statistics from a test you ran yourself in April following up on a request made by Don. From your e-mail: "Of those [domains] I found MXes for 862 of them, and 414 of the domains had mail servers that support EAI. As you can see from this summary, 85% those have mail hosted at gmail, 10% at Microsoft."

Regards,

A bit of a changelong: John's EAI issue has been addressed;

Thanks for the update, but I regret to say that your test of the domain's MTA while sort of interesting, tells you nothing about whether the site you tested could actually send mail to the address you entered.  Sites that sign up large numbers of people use CRM or e-commerce software which sends the mail through a specialist provider like Salesforce or Mailchimp or Sendgrid, so it depends on that provider's EAI support.  The server you tested is for the company's office mail.

The only way to see if the mail works is to get far enough in the signup process that it sends a message to the address you entered, which I realize is more than you're funded to do.  But to get real useful results, that's what we need in the future.

Marc: We don't know the legality of making the website data available, and I don't feel very inclined to take another swim at ICANN Legal's pool. Perhaps the leadership can set this consultation as a goal. We handed the csv of the results over to them.

Yeah, dealing with legal is usually a losing battle.
