Popmail.py Need help.....................

[Relfx]

I have tried using these modules but i'm getting some errors when i run the
script.

Here is the code i'm using for the pop mail :

import getpass , poplib
M = poplib.POP3('pop.mail.mia.bellsouth.net')
M.user(getpass.getuser())
M.pass_(getpass.getpass())
numMessages = len(M.list()[1])
for i in range (numMessages):
    for j in M.retr (i+1)[1]:
        print j

>>>
Traceback (most recent call last):
  File "<string>", line 1, in ?
  File "C:\Python21\Scripts\popmail.py", line 2, in ?
    M = poplib.POP3('pop.mail.mia.bellsouth.net')
  File "C:\PYTHON21\lib\poplib.py", line 79, in __init__
    self.sock.connect((self.host, self.port))
  File "<string>", line 1, in connect
