需要帮助通过具有自定义域的 Office 365 SMTP 发送电子邮件

Question

我需要能够从托管在office365中的

[email protected]

向用户发送电子邮件。我的项目的电子邮件后端设置文件如下所示

# Email settings
EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend"
EMAIL_HOST = "smtp.office365.com"
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = "[email protected]"
EMAIL_HOST_PASSWORD = "App_password"

我目前面临的具体错误消息是[

Authentication unsuccessful, the request did not meet the criteria to be authenticated successfully. Contact your administrator.

]

我已验证登录凭据，并尝试了

587

和

25

两个端口，但问题仍未解决。

**但是，**

我能够使用

smtp-mail.outlook.com

以及

@outlook.com

电子邮件地址

成功发送电子邮件

EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend"
EMAIL_HOST = "smtp-mail.outlook.com"
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = "[email protected]"
EMAIL_HOST_PASSWORD = "App_password"

我认为这与发送电子邮件的功能无关。

def send_email_verification(user):
    site_url = "https://www.example.com"
    print("Trying to send email")

    if user.is_active:
        return
    else:
        print("sending email")
        confirmation_token = default_token_generator.make_token(user)  # unique token
        activation_link = f"{site_url}/users/api/users/activate/{user.id}/{confirmation_token}"   # activation link to be sent in email

        subject = "Verify your Email address"
        from_email = settings.EMAIL_HOST_USER
        to_email = user.email


        # Load the email template and render it with the activation link
        html_content = render_to_string('email_verification.html', {'activation_link' : activation_link})
        text_content = strip_tags(html_content)         # This strips the html, so people will have the text.


        # Create the email, message and send it.
        msg = EmailMultiAlternatives(subject, text_content, from_email, [to_email])
        msg.attach_alternative(html_content, "text/html")

        try:
            msg.send()
            print(f"Email successfully sent to {user.email}")
            print(f"confirmation toke = {confirmation_token}")
        except Exception as e:
            print(f"an error  has occured while sending email : {e}")

Office 365 不再允许基本身份验证。请参阅https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/authenticated-client-smtp-submission
