我正在尝试通过Amazon SES从django应用发送邮件，但我不断收到以下错误：

  

smtplib.SMTPSenderRefused：（501，b'Invalid MAIL FROM address   提供'，'=？utf-8？q？AKIAWMDVL5UEWNT3ODOO？='）

这些是我正在使用的设置：

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'email-smtp.ap-south-1.amazonaws.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'smtp credential key'
EMAIL_HOST_PASSWORD = 'smtp credential password'
EMAIL_USE_TLS = True

这是代码：

class CompanyCreateAPIView(APIView):
    permission_classes = (permissions.AllowAny,)
    def post(self,request):
        email = request.data["company_email"]
        phone = request.data["company_phone"]

        def random_with_N_digits(n):
            range_start = 10 ** (n - 1)
            range_end = (10 ** n) - 1
            return randint(range_start,range_end)

        code = random_with_N_digits(4)

        subject = 'Comapny Creation'
        message = 'Company Code is {}'.format(code)
        email_from = settings.EMAIL_HOST_USER
        recipient_list = [str(email),]
        send_mail(subject,message,email_from,recipient_list)

我尝试更改端口，但是它不起作用，我已经在SES中验证了电子邮件地址。我丢失了什么？
