I was thinking about this, too. 

O365 allows “bring your own domain name”.  Most of these are .COM, but I know we have multiple .REALTOR so any TLD could be represented.

Or have you already made that distinction based on SMTP responses?

It may be good idea to skip the testing of domains on .com or any other tld which are hosted on google / Microsoft / XgenPlus / Coremail for MX. That does not give us correct picture of large setups.

>  If I read it correctly, I am surprised at that more than 10 percent of COM domain names are eai ready now. It is a very big number.

I redid the checks to be sure. I sampled 3655 mail servers that handle
10372 domains in .com. Of those, 200 servers handling 1417 domains
announced SMTPUTF8, so it`s 5.5% of the servers or 13.7% of the domains.

That`s because both gmail and outlook.com handle a lot of domains on
relatively few IPs.

>  This has some interesting findings:
>
>  We now have a baseline measurement of EAI Readiness so we can measure progress over time. NB: This is all EAI Phase 1 readiness, the ability to Send To and Receive From all email addresses. This does not address the issue of being able to host an EAI address. That’s being done in a separate effort.
>  We also have a list of the large MTAs (that announce their platform). This will be useful as we pursue the last phase of the EAI Evaluation.
>  We’ve also seen the impact of Microsoft’s online facilities becoming EAI ready earlier this year.
>  The EAI Readiness by TLD is potentially interesting. I’ve asked John to see if there are any marked differences with IDN TLDs.

>  Before John does any more work on this, I’m putting it out to this group for comments.
