问题
在学习用Django写一个博客的过程中，需添加一个邮件分享功能，在使用QQ邮箱发送邮件的时候碰到了问题。
在设置文件settings.py中添加以下设置:
EMAIL_HOST = 'smtp.qq.com'
EMAIL_HOST_USER = '2460490819@qq.com'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
使用manage.py提供的shell工具进行测试：
panzeyan@panzeyan-S400CA:~/PycharmProjects/myDjangoProject/mysite$ python3 manage.py shell
Python 3.5.1+ (default, Mar 30 2016, 22:46:26)

>>> from django.core.mail import send_mail
>>> send_mail("learn django", "step by step", "2460490819@qq.com",['2460490819@qq.com'], fail_silently=False)
抛出异常：
Traceback (most recent call last):

思路和解决方法
忽略ImportError，关注SMTPAuthenticationError。猜测是QQ邮箱SMTP服务的授权问题导致发送邮件失败。
打开异常末尾给出的链接：
http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256
QQ邮箱需使用授权码作为专用密码，登录第三方客户端，所以用原来的密码会导致错误。
按照链接中的提示，进入QQ邮箱设置页面，开启SMTP服务，发短信获取授权码。然后在settings.py中将16位授权码赋值给EMAIL_HOST_PASSWORD。
EMAIL_HOST_PASSWORD = 'shlvewmsheooebhd'
进入manage.py提供的shell工具进行测试：
>>> from django.core.mail import send_mail
>>> send_mail("1", "2", "2460490819@qq.com", ['2460490819@qq.com'], fail_silently=False)
1
1表示发送成功。登录邮箱，成功收到邮件，问题解决。
