Django从docker容器发送邮件

我有一个Django应用程序，当我在本地运行它时，一切正常。但是在docker容器中运行的生产中，它不能再发送邮件了，我得到了一个错误

Traceback (most recent call last):

我正在使用以下设置：

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'me@gmail.com'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_PORT = 587

---

有人知道我做错了什么吗？

我会从生产主机的端口587检查到目标主机smtp.gmail.com的连接状态。

Docker容器是否打开了邮件端口？这是什么端口？它在您的设置中：

EMAIL\u port=587

显然与Docker或django。我在承载该站点的服务器上没有打开邮件端口。
