* 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.
loMailman = CreateObject('Chilkat.MailMan')

* 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.
loMailman.HttpProxyHostname = "www.my-http-proxy.com"
loMailman.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
loMailman.MailHost = "pop.example.com"

* Set the POP3 login/password.
loMailman.PopUsername = "myLogin"
loMailman.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.
