All emails to my att.net email account are bouncing
I suddenly have need of my att.net email account (haven't used it in years).
I can log in just fine. I can also send email just find (i.e. it's received by the addressee). However, if I try to send email to my account, it gets bounced back. I have tried from multiple email services (Zoho, Google, even my internal att.com account), and they all bounce.
So I created a new email account on att.net. Same exact problem. So I feel fairly confident it's not the account. Here's the error I get in the bounce message (I replaced the actual email IDs with REDACTED):
