我已经安装了Open edX bitnami ami并对其进行了测试 . 我遇到smtp电子邮件配置问题 . 我按照这里的说明进行操作：Bitnami Open edX - How to configure outbound email settings但这不起作用 . 电子邮件未发送，我无法通过查看日志文件来查找原因 . 然后我按照这里的配置：Enable SMTP for EDX (Production Stack)并使用 mandrill smtp邮件服务配置了 postfix . 从服务器，此命令有效：

sendemail -f registration@myedx.com -t mymail@gmail.com -m "Message Body" -u "Message Subject"

但形成 edX 实例我收到错误 . edx.log 文件如下所示：

不知道如何解决这个问题？或者如何在bitnami edX 实例中激活smtp电子邮件？

python django smtp edx
