Who is your email account with, Gmail, Aol, Yahoo, Outlook.com, etc etc ?
Thank you. Lets check a few things. And then probably a few more!
Start with, when you are viewing your yahoo inbox. Click the gear at the top right. Then click settings.
Then click writing email. Do you have any send only addresses set? If so, delete them. Thats probably how the mails are being sent.
If you dont see any send only addresses. Go to security ( on the settings screen ) And check disposable addresses. If you have any disposable addresses set. Delete those as well.
Let me know if you found either. And if not, we will discuss further options.

Going back to the settings window. Accounts page.. What do you see there?
To clarify, the only address you see listed there.. Is exactly the same as your full yahoo / att address?
If thats the case.. Then check your account security window.
Do you have any on demand passwords set? Unknown phone numbers, recovery addresses?
And one last thing, on the account settings window.
Check the recent activity.. Is it showing anyone logging in from somewhere outside your zip code or area?
