Demonstrates how to communicate with a POP3 server through an HTTP proxy. Tcl

#  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.example.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.
