#  The mailman object is used for receiving (POP3)
#  and sending (SMTP) email.
mailman = chilkat.CkMailMan()

#  Any string argument automatically begins the 30-day trial.
success = mailman.UnlockComponent("30-day trial")
if (success != True):
    print("Component unlock failed")
    sys.exit()

#  To connect through an HTTP proxy, set the HttpProxyHostname
#  and HttpProxyPort properties to the hostname (or IP address)
#  and port of the HTTP proxy.  Typical port numbers used by
#  HTTP proxy servers are 3128 and 8080.
mailman.put_HttpProxyHostname("www.my-http-proxy.com")
mailman.put_HttpProxyPort(3128)

#  Important:  Your HTTP proxy server must allow non-HTTP
#  traffic to pass.  Otherwise this does not work.

#  Set the POP3 server's hostname
mailman.put_MailHost("pop.someMailServer.com")

#  Set the POP3 login/password.
mailman.put_PopUsername("myLogin")
mailman.put_PopPassword("myPassword")

#  Copy the all email from the user's POP3 mailbox
#  into a bundle object.  The email remains on the server.
# 
#  NOTE: All methods that communicate with a POP3 server
#  will automatically connect and authenticate (i.e. login)
#  if not already connected.  The connection will remain
#  open after the method call returns so that subsequent
#  calls do not need to re-establish the connection.
#  In this case, the connection is established via the HTTP
#  proxy.
# bundle is a CkEmailBundle
bundle = mailman.CopyMail()

if (bundle == None ):
    print(mailman.lastErrorText())
    sys.exit()

for i in range(0,bundle.get_MessageCount()):
    # email is a CkEmail
