After changing my passwords, I tried to send an email to my alternate account and received a "sending message" notice.  I left it in sending message for over an hour.  I closed the sending message.  Then checked all of the account settings and preferences, and changed one setting to "normal password", and repeated the test, I receive the same results.  Using "Software Manager" I uninstalled "ThunderBird" then re-installed "ThunderBird" via  the gui.  I tried the same test, and again received the same results.

    I again went back to the Comcast office and reported my results, I was told that there were 2 other complaints about the same situation, I asked what their solution was and was told to just log into my Comcast Account online to send emails.  I asked them what did Comcast do that caused this problem, I was informed that they are just a sales office, I asked for a phone number for tech support and was told that they don't have a phone number to tech support.

    So, it seems I am on my own to fins a solution to the situation they caused, can you help?

    If there is any further information you need feel free to ask.

I live in Peoria, Il USA. our service provider is Comcast. I use Linux Mint Cinnamon 21.3 ver 6.0.4. Just about a month ago, I found I was not able to send emails. I can receive emails easy, but not send on either of the 2 email accounts on my desktop computer. When I tried to send a message I received an error telling me I didn't have permission, so I took pictures of the error messages to the local Comcast office. They told me I needed to change my password. After changing my passwords, I tried to send an email to my alternate account and received a "sending message" notice. I left it in sending message for over an hour. I closed the sending message. Then checked all of the account settings and preferences, and changed one setting to "normal password", and repeated the test, I receive the same results. Using "Software Manager" I uninstalled "ThunderBird" then re-installed "ThunderBird" via the gui. I tried the same test, and again received the same results.
