我在使用 Django 从联系表单发送邮件时遇到问题。我在 settings.py 中设置了 smtp 配置，我可以从本地发送它。但在生产服务器中，我收到 504 网关超时错误。这是错误日志的内容。

你有什么想法吗？

【问题讨论】：

安装了sendmail？

标签： django apache nginx mod-wsgi

【解决方案1】：

您的应用无法连接到指定的 SMTP 服务器。检查以下问题：

您的 SMTP 详细信息是否正确？
您在配置的主机/端口上是否有正在运行的 SMTP 服务器？
连接是否被防火墙阻止？

从日志中可以明显看出 SMTP 连接超时。请提供更多详细信息（代码/配置）以更好地推测。

【解决方案2】：

好吧，masnum 是对的。我已经更改了端口并禁用了 TLS 使用并且它可以工作。但我有两个问题。我的配置如下：

EMAIL_PORT = 587
EMAIL_USE_TLS = True

这是正确的吗？我可以在 localhost 中使用它，为什么不能在生产服务器中使用？可能是繁忙的港口？

还有另一个问题。我用这个：

try:
            send_mail(subject, message, from_email, ['info@domain.com'])
        except BadHeaderError:
            messages.warning(request, 'Ha ocurrido un fallo. Inténtelo de nuevo más tarde.')
            return render(request, "contacto.html", {'form': form})

        except TimeoutError:
            messages.warning(request, 'Ha ocurrido un fallo. Inténtelo de nuevo más tarde.')
            return render(request, "contacto.html", {'form': form})

为什么错误没有被 TimeoutError 而不是 504 Apache 捕获？
