When I try to send an email message through Thunderbird, I get two error messages that say basically the same thing - that I need to provided a password to the outgoing server smtp.comcast.net. I don't know what that password, but I know that it is NOT the password that I use to log into my comcast.net email account via the web. I followed the directions about the port settings and the encryption settings, but the problem is not there. Trying to get past Comcast's chatbot and voicemail bot to explain problem to a human is a nightmare which I have not yet accomplished.
