我在docker-composer.yml上为email_settings添加了一个新的.py文件(保存在tcms_settings_dir上(，并重新启动docker容器以刷新设置并获得新文件。email_config文件如下：
import os
import pathlib
import tempfile
from importlib import import_module
import pkg_resources
from django.contrib.messages import constants as messages
from django.urls import reverse_lazy
from django.utils.translation import gettext_lazy as _
import tcms
SERVER_EMAIL = DEFAULT_FROM_EMAIL = 'my@emailcom'
# additional Kiwi TCMS setting
EMAIL_SUBJECT_PREFIX = '[Kiwi-TCMS] '
EMAIL_HOST = 'mail.my_server.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'admin@email.com'
EMAIL_HOST_PASSWORD = 'my_pass'
EMAIL_USE_TLS = True
然后我尝试：sudo docker exec-it kiwi_web/Kwi/manage.py发送测试电子邮件my_email@email.com
我得到以下错误：

我已经检查了托管docker容器的计算机是否可以连接到smtp服务器(ping(，并且smtp设置是否正确，因为它们目前正在laravel项目中使用。我不知道是否必须打开docker容器上的端口才能与smtp服务器通信。
你能帮助解决可能导致这种情况的原因吗？
假设您的配置是正确的，则此错误是一般的网络错误。网络层本身可能会出现很多问题。
- 您是否尝试验证您的设置是否正确
- 您是否验证了容器和SMTP服务器之间的网络连接？例如使用一些命令行工具
- 您是否检查了防火墙和实际SMTP配置中是否存在明显的问题，如允许/阻止特定端口和地址
所需操作：如果您想在此处取得任何进展，请在原始问题中提供以上所有信息。
更新：提供的详细信息仍然没有帮助，因为这个错误太过普遍，无法理解发生了什么。这是某种网络问题，但如果不能访问运行容器的系统(并公开电子邮件凭据(，我们就无法调试任何内容。
