无法设置邮件发送的smtp。

Question

我为email_settings添加了一个新的email_settings文件(保存在tcms_settings_dir上)，并重新启动了docker容器，以刷新设置并获取新文件。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

然后我尝试使用: sudo exec -it kiwi_web /Kiwi/manage.py sendtestemail my_email@email.com

我得到了以下错误：

Traceback (most recent call last):

我已经检查了承载坞容器的计算机是否可以与smtp服务器(pinged)连接，并且smtp设置是正确的，因为它们目前正在一个laravel项目中使用。我不知道是否必须打开码头容器上的端口才能与smtp服务器通信。

你能帮我弄清楚是什么原因造成的吗？

Answer 1

假设您的配置是正确的，则此错误是一般的网络错误。在网络层本身，有太多的事情会出错。

• ，您是否试图验证您的设置确实正确？
• ，您是否验证容器和SMTP服务器之间的网络连接？例如，使用一些命令行工具？
• ，您是否检查防火墙和实际SMTP配置中是否存在明显的问题，如允许/阻塞特定端口和地址?

。

操作要求:如果您想在这里取得任何进展，将在原始问题中提供所有上述信息。

更新：提供的细节仍然没有帮助，因为这个错误太笼统，无法理解正在发生的事情。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东西。
