Outgoing email stopped working
I have a bellsouth.net email address.
This morning email (POP) stopped working on all my devices. (Could not send or receive.) I was forced to logon to Yahoo, agree to new terms, and now I can receive email again.
However, outgoing SMTP is no longer working. I have deleted and readded the accounts and Ive used both the ATT settings (outgoing.att.net) as well as the Yahoo settings. I get failures in Thunderbird (An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again) and on my mail client on my phone.
I am using a different reply-as address since I use this email account for business purposes and have a mail-forwarding account thru a professional organization. I had to "verify" this address several years ago. I assume the issue is that something has changed either at Yahoo or ATT and I need to re-verify but I cannot any information on how to do this on either the Yahoo or ATT pages. How do I use a different reply-as address from my email client using a bellsouth.net email address.
