IMAP using SOCKS5, SOCKS4 Proxy

Demonstrates how to connect to an IMAP server through a SOCKS5 or SOCKS4 proxy. VB.NET

Dim success As Boolean = False

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim imap As New Chilkat.Imap

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

' Connect to an IMAP server through the SOCKS proxy.
' Use TLS
imap.Ssl = True
imap.Port = 993
success = imap.Connect("imap.example.com")
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Login
success = imap.Login("myLogin","myPassword")
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Get the message IDs of all the emails in the mailbox
' We can choose to fetch UIDs or sequence numbers.
Dim fetchUids As Boolean = True
Dim messageSet As New Chilkat.MessageSet
success = imap.QueryMbx("ALL",fetchUids,messageSet)
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Fetch the emails into a bundle object:
Dim bundle As New Chilkat.EmailBundle
Dim headersOnly As Boolean = False
success = imap.FetchMsgSet(headersOnly,messageSet,bundle)
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Loop over the bundle and display the FROM and SUBJECT of each.
Dim email As New Chilkat.Email
Dim i As Integer = 0
Dim numEmails As Integer = bundle.MessageCount
While i < numEmails

    bundle.EmailAt(i,email)

    Debug.WriteLine(email.From)
    Debug.WriteLine(email.Subject)
    Debug.WriteLine("--")
