Django和Mailgun:552抱歉，您的信封发件人域必须存在（#5.7.1）

Question

我试图通过Anymail包和OVH服务器使用Django和Mailgun发送邮件。

我目前收到552抱歉，您的信封发件人域必须存在（#5.7.1）错误。

在这个问题/答案中，有人建议我需要一个“from”标题，但我得到的回复似乎表明标题已经包括在内：

    "headers": {
      "to": "[e-mail]",
      "message-id": "[e-mail]",
      "from": "[e-mail]",
      "subject": "Mail test !"
    },

以下是完整的答复，供参考：

    ],
    "size": 643
  },
  "recipient": "[e-mail]",
  "id": "TfJKwpoZQq6bM-MW5sm6nA"
}

这是我的Django代码：

def SendTestEmail(request):
    if request.user.is_staff and settings.DEBUG == True :
        send_mail(
            subject='Mail test !',
            message='''Bonjour {}, votre email a bien été envoyé.'''.format(request.user.get_full_name()),
            recipient_list=['[e-mail]',],
            from_email=settings.DEFAULT_FROM_EMAIL,
            fail_silently=False,
        )
        messages.success(request, 'Email correctement envoyé !')
    return redirect('rideshare_event_list')

Answer 1

尝试使用[e-mail]作为您的发件人地址，而不是[e-mail]。

恐怕我不确定是否可以使用[e-mail]作为发件人地址。
