Here is a minimal example (without error checking) that opens a mailbox and retrieves and prints all messages:
import getpass, imaplib, string M = imaplib.IMAP4() M.login(getpass.getuser(), getpass.getpass()) M.select() typ, data = M.search(None, 'ALL') for num in string.split(data[0]): typ, data = M.fetch(num, '(RFC822)') print 'Message %s\n%s\n' % (num, data[0][1]) M.logout()
