BRING BACK OLD DOMAIN!
Please bring back old domain like ymail.com,
We the users have a lot of problem due to inability to choose the email while we're making the email .
In the past, depending on where you were when you signed up for your Yahoo Mail account, you were given a different domain other than just @yahoo.com.
You can no longer create accounts with Yahoo domains other than “@yahoo.com”. More info here: https://help.yahoo.com/kb/identify-domain-extension-yahoo-mail-sln2153.html
