I had to change my Google password and that meant I had to use the new password to open G-mail in Thunderbird. With your help I was able to change the password in Thunderbird and I am able to download e-mail to my inbox. But when I try to send an e-mail I get the following error message: Login to server smtp.gmail.com with (my username).gmail.com failed. I had changed the password for the only gmail account in password manager smtp://smtp.gmail.com. oauth://accounts.google.com that has my email address as the username changes the password every time the program is opened. Where do I enter a password specifically for smtp outgoing mail?
