Reference: Yahoo Email Domains

Looking for a list of all of Yahoo's consumer email domains? AOL, Verizon and Yahoo have merged and the resulting entity is called OATH. You can find a list of all OATH domains, as well as Microsoft domains and Google domains here.


  1. I have "recorded" a lot of different domains pointing to yahoo MXs.

    There are the ones missing from your list and for which I recorded opens in the last 2 months:

    those domains IMHO are yahoo domains (like rocketmail):

    I don't have opens from (the only one from your list).

    There also a lot (thousands) of minor domains that points to a "biz" mx, so I guess they are hosted by yahoo, too.

  2. You forgot,,, ymail,com,,,,,,,,,

    These are all email domains Yahoo hosts for AT&T companies.

  3. It is true that AT&T users have the ability to use Yahoo webmail to read their email. But, the AT&T domains have separate MXes and separate spam filtering. It's possible to be blocked or bulking at Yahoo but not at AT&T. So I likely would not put them in the same category.
