I added 2 email accounts to Thunderbird a few months ago and it all worked but now i'm unable to download or send messages. It downloaded the messages last time in August. Now it does not work. If i try to download messages - no errors, just downloading nothing but if i try to send a message then it gives me SMTP timeout error. Tried to add new account but recieve "Unable to login at server" error for all accounts i try to add. Created a new profile, and turned off firewall but problem persists.
