主要是填入邮箱的就MAIL_USERNAME,MAIL_PASSWORD，FLASKY_MAIL_SENDER三个吧？不知道是不是还漏了什么
shell下是非异步的时候成功的，加了异步很奇怪没有收到邮件
大家无视注释。。目前在学习，做个标记免得忘了= =
感谢大神帮忙

Answer 1

找到原因了，os.environ.get得去掉，取代的是邮箱的字符串就行了。

app.config['MAIL_SERVER'] = 'smtp.qq.com'
app.config['MAIL_PORT'] = 587
app.config['MAIL_USE_TLS'] = True
app.config['MAIL_USERNAME'] = '邮箱@qq.com'
app.config['MAIL_PASSWORD'] = '授权码'

app.config['FLASKY_MAIL_SUBJECT_PREFIX'] = '[Flasky]'
app.config['FLASKY_MAIL_SENDER'] = '你的邮箱'
app.config['FLASKY_ADMIN'] = '你的邮箱'

Answer 2

亲，我也遇到这个问题了啊，改了还是有问题呀。不太明白这几个邮箱的关系。
