django - 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。但是在运行于Docker容器中的生产中，它无法再发送邮件了，我收到了错误

Traceback (most recent call last):

    sock.connect(sa)
OSError: [Errno 99] Cannot assign requested address

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 = '[e-mail]'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_PORT = 587

有人知道我在做什么错吗？

最佳答案

我会从您的生产主机在端口587处检查到目标主机smtp.gmail.com的连接状态。
