I live out in the country now. I have the only internet provider who comes out here - Frontier.com. They do not give an email address to new customers. So I do NOT have an email ending with @frontier.com to set up the connection to my new internet provider via Thunderbird. I've tried every possible configuration to try to get Thunderbird to connect without an actual @frontier.com email address. Frontier wanted me to use an already present att email with them. But obviously Thunderbird knows I don't have an att account!! So how the heck do I get Thunderbird to connect to my internet without an @frontier.com email!!!!???? I have manually configured the settings over and over with different emails trying to get it to connect without any luck. I have spent days on this. I have talked to Frontier many times and been hung up on when I get to the obvious question of how can I connect to the internet in my email program without an @frontier.com email. I am afraid that I will have to try some other program to be able to get my emails..... but I don't want to!!
