# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# The mailman object is used for receiving (POP3) 
# and sending (SMTP) email.
set mailman [new_CkMailMan]

# 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.
CkMailMan_put_HttpProxyHostname $mailman "www.my-http-proxy.com"
CkMailMan_put_HttpProxyPort $mailman 3128

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

# Set the POP3 server's hostname
CkMailMan_put_MailHost $mailman "pop.someMailServer.com"

# Set the POP3 login/password.
CkMailMan_put_PopUsername $mailman "myLogin"
CkMailMan_put_PopPassword $mailman "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
