SOCKS4, SOCKS5 Proxy for POP3

Demonstrates how to communicate with a POP3 server through a SOCKS4 or SOCKS5 proxy. VB.NET

Dim success As Boolean = False

' This example requires 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.
Dim mailman As New Chilkat.MailMan

' To use a SOCKS4 or SOCKS5 proxy, simply set the following
' properties prior to making any calls that communicate with
' a POP3 server:
' The SOCKS hostname may be a domain name or 
' IP address:
mailman.SocksHostname = "www.mysocksproxyserver.com"
mailman.SocksPort = 1080
mailman.SocksUsername = "myProxyLogin"
mailman.SocksPassword = "myProxyPassword"
' Set the SOCKS version to 4 or 5 based on the version
' of the SOCKS proxy server:
mailman.SocksVersion = 5
' Note: SOCKS4 servers only support usernames without passwords.
' SOCKS5 servers support full login/password authentication.

' 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.
Dim bundle As New Chilkat.EmailBundle
Dim keepOnServer As Boolean = True
Dim headersOnly As Boolean = False
' Irrelevent because we are NOT downloading headers-only
Dim numBodyLines As Integer = 0
success = mailman.FetchAll(keepOnServer,headersOnly,numBodyLines,bundle)
If (success = False) Then
    Debug.WriteLine(mailman.LastErrorText)
    Exit Sub
End If


Dim email As New Chilkat.Email
Dim i As Integer = 0
While i < bundle.MessageCount
    bundle.EmailAt(i,email)

    Debug.WriteLine("From: " & email.From)
    Debug.WriteLine("Subject: " & email.Subject)
    i = i + 1
End While
