VBScript Requires Chilkat v11.0.0+

POP3 using HTTP Proxy

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

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

'  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 = 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.
mailman.HttpProxyHostname = "www.my-http-proxy.com"
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
mailman.MailHost = "pop.example.com"

'  Set the POP3 login/password.
mailman.PopUsername = "myLogin"
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.
