Question

从Django的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，我得到504网关超时错误。这是错误日志内容。

有什么想法吗？

Answer 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详情是否正确？
您在配置的主机/端口上有运行的SMTP服务器吗？
连接是否被防火墙阻止？

从日志中可以看出，SMTP连接已超时。请提供更多详细信息（代码/配置）以便更好地推测。

Answer 2

好的masnum是对的。我已经更改了端口和无法使用的TLS，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

这是对的吗？我可以在localhost中使用它，为什么不在生产服务器中？繁忙的港口可能吗？

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TimeoutError没有捕获错误而不是504 Apache？
