The missing emails could be in either your "Spam" or "Trash" folder. If you don't see these folders in Yahoo!mail, click the 
button. You need to open those folders to check for new email because Yahoo doesn't indicate unread messages in them.
Tried still didn’t get it. I even tried their filters to allow anything that has a .gov in the domain. Got nothing. If anyone else is getting email thru yahoo from the social security please let us know how. Thanks
Hi dlkimbro,
I'm sorry that you're not receiving from a specific sender. You may consider reporting the issue to Yahoo's support team so they look into any issues with the domain or filters. I apologize for the trouble.
I originally reported the problem to tech support and was assured it wasn't Yahoo but the rep claimed he reported it. The rep was self-assured and, at best, smug. It hasn't been solved, Social Security Admin flatly blames Yahoo and I think they're right. Shameful for all the finger pointing and lack of quality tech support.
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.
