Django 3，G Suite的联系表格-电子邮件发送错误

Question

目标

• 在Django 3构建的Digital Ocean上部署登录页
• 将我的G套件帐户添加到联系人表单中，这样人们就可以键入他们的电子邮件、主题和消息并将其发送给我

我做了什么

• 我根据以下指南建立了联系
• 我已经测试过了，它会打印出终端中的所有参数

Content-Type: text/plain; charset="utf-8"
MIME-Version: 1.0
Content-Transfer-Encoding: 7bit
Subject: helllo
From: [e-mail]
To: [e-mail]
Date: Tue, 17 Mar 2020 14:29:40 -0000
Message-ID: <[e-mail]>
This is the message.

• 完成教程后，我将以下内容添加/切换到settings.py文件

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp-relay.gmail.com' 
EMAIL_HOST_USER = '[e-mail]' 
EMAIL_HOST_PASSWORD = 'mypassword'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

• 我购买了一个G Suite订阅，其中包含G Suite SMTP中继服务，每天可以发送10’000封电子邮件

错误

1.第一次跑步后，我收到了以下电子邮件：

Sign-in attempt was blocked
[e-mail]
Someone just used your password to try to sign in to your account from a non-Google app. Google blocked them, but you should check what happened. Review your account activity to make sure no one else has access.
Check activity

2.第二次运行后，我在浏览器中收到以下错误消息(没有电子邮件(

SMTPAuthenticationError at /email/

Request Method: POST
Request URL:    http://127.0.0.1:8000/email/
Django Version: 3.0

3.在谷歌帮助聊天和切换一堆设置后，再次运行相同的代码
