Taiga docker: Email NOT works with SMTP

Hi there,
I just did a fresh install of Taiga on my Docker host and after a few issues I managed to get it to work but no matter what, the email is not working. Following is the screen snapshot (insides there are my .env file and my ./taiga-manage.sh test_emails xxx@xxx.com command result)


why is ConnectionResetError: [Errno 104] Connection reset by peer ? Anyone can help, please?

It 's working now. The reason was - There was a special Symbolic Character in my password. I changed that, so it works.
Thanks a lot.
