Flask学习之十一邮件支持
完了之后我因为多次测试出现服务器拒绝了发件人地址，然后我到现在还没找到解决办法，于是乎又换了163邮箱= =
SMTPSenderRefused: (503, 'Error: need EHLO and AUTH first !', u'username@qq.com')

终于找到解决办法了
把hello.py下面两项config直接填进去可以解决，如下

app.config['MAIL_USERNAME'] = '1234567890@qq.com'
# 注意两边带''，字符串类型
app.config['MAIL_PASSWORD'] = '授权码'
# 注意两边带''

####我想应该是在cmd中写入密码和授权码，但是环境没有接受到的关系，基本可以确定qq邮箱设置是对的，出问题和他没关系

备注，如果用163邮箱，配置要改成：
复制代码

# mail server settings
MAIL_SERVER = 'smtp.163.com'
MAIL_PORT = 587
MAIL_USE_TLS = True
MAIL_USE_SSL = True
MAIL_USERNAME = os.environ.get('MAIL_USERNAME')
MAIL_PASSWORD = os.environ.get('MAIL_PASSWORD')
# administrator list
ADMINS = ['your-username@163.com']

复制代码
TLS要改成True，否则会出现以下错误：

smtplib.SMTPServerDisconnected: Connection unexpectedly closed

这里写图片描述
如果你按照cmd里面的设置环境变量的方法set，那么，你就会碰到授权错误553或者550的信息，如下：

那就试试powershell吧。
