Python读取邮箱邮件

代码示例：

from email.parser import Parser
from email.header import decode_header
from email.utils import parseaddr
import poplib



# 输入邮件地址, 口令和POP3服务器地址:
# email = input('Email: ')
# password = input('Password: ')
# pop3_server = input('POP3 server: ')

# 新浪邮箱测试通过, 密码使用登陆密码
# email = "[email protected]"
# password = "password"
# pop3_server = "pop.sina.cn"


# qq邮箱测试通过， 使用授权码， 使用ssl
# email = "[email protected]"
# password = "titeexrfwjutbhhg"
# pop3_server = "pop.qq.com"
