我是 Kiwi TCMS 的新手，我仍在开发环境中，试图启动并运行它。
我在我的电脑上使用 Ubuntu 18.04。Docker 容器（kiwi_web 和 kiwi_db）已启动，据我所知它们工作正常。
我的问题是我无法让 Kiwi 发送电子邮件。
我已经阅读了docker-compose.yml文件中的卷，如下所示：
- ./local-settings/:/venv/lib64/python3.6/site-packages/tcms/settings/
然后，我在./local-settings/local_settings.py里面创建了这个：
EMAIL_HOST = 'smtp.server.com'
EMAIL_PORT = '485'
EMAIL_HOST_USER = 'admin@server.com'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_USE_TLS = True
但它没有用。
这是回溯：
