//  See Global Unlock Sample for sample code.

//  The mailman object is used for receiving (POP3) 
//  and sending (SMTP) email.
oMailman := 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.
oMailman:HttpProxyHostname := "www.my-http-proxy.com"
oMailman: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
oMailman:MailHost := "pop.example.com"

//  Set the POP3 login/password.
oMailman:PopUsername := "myLogin"
oMailman: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.
