Python read mail messages

Code Example:

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



# Enter the e-mail address, password and POP3 server address: 
# In Email = INPUT ( 'In Email:') 
# password = INPUT ( 'Password:') 
# pop3_server = INPUT ( 'POP3 Server:')

# Sina-mail test passes, password login password 
# Email = "[email protected]" 
# password = "password" 
# pop3_server = "pop.sina.cn"


# QQ mailbox by testing, using the authorization code, use the ssl 
# Email = "[email protected]" 
# password = "titeexrfwjutbhhg" 
# pop3_server = "pop.qq.com"
