// 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.
loo_Mailman = create oleobject
// Use "Chilkat_9_5_0.MailMan" for versions of Chilkat < 10.0.0

// 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.
loo_Mailman.HttpProxyHostname = "www.my-http-proxy.com"
loo_Mailman.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
loo_Mailman.MailHost = "pop.someMailServer.com"

// Set the POP3 login/password.
loo_Mailman.PopUsername = "myLogin"
loo_Mailman.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.
