I can no longer send email from my Thunderbird app with xfinity email accounts. I have spent many hours yesterday and today with xfinity security techs, but they have not fixed anything and have no idea what is causing this. Before last night at 9pm it has been working fine for years and years. I can receive email for these accounts in thunderbird, but can only send email from my primary xfinity account. Please help?

Do you have separate smtp servers for each account, or are they all set to send through the smtp for the primary account?
