Hi Mitchella and Dlkimbro, I'd be distressed if I wasn't able to receive my necessary verification emails, and I apologize this has been happening since your addresses transitioned to Yahoo. I understand the importance of utilizing two-step verification when accessing your accounts! Have you checked your Spam and Trash folders to see if mail is being misidentified? Also, be sure to add the social security.gov email address to your saved Contact list. Yahoo Support has additional suggestions: https://help.yahoo.com/kb/SLN28074.html;_ylt=AwrihfMcYIRmTAQAWXVXNyoA;_ylu=Y29sbwNiZjEEcG9zAzIEdnRpZAMEc2VjA3Ny. Also, follow the steps on this page and send yourself a test email to see if you receive an error message or a bounceback email that includes a failed delivery message and error number.
This is a problem with the Yahoo mail server, and involves many sites that use email for authentication or verification such as any bank or credit card site, discord, facebook, physics forums, quora, reddit, stackoverflow, ... . In the case of reddit, regular emails are received, but verification emails are not received. In the case of an older Facebook account created with a single cox email address, those users can no longer access their Facebook account, and Facebook does not offer any means of support to regain access to accounts when emails are broken such as Cox switching to Yahoo mail servers. Yahoo support falsely claims the problem doesn't exist and refuses to do anything about the problem.
