After updating Thunderbird to Ver 78, I can no longer send or receive messages using my internet service provider att.net. I'm guessing it's because Thunderbird's improved security protocalls are not compatible with those used by att.net. Is it possible to install Ver 68 in order to go back to security protocalls that were compatible with att.net ? I can send and receive emails with no problems using the att.net web page.
