(Go) POP3 using HTTP Proxy

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

Chilkat Go Downloads Go Package for Windows, MacOS, Linux, Alpine Linux, Solaris

    // 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.
    mailman := chilkat.NewMailMan()

    // 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.SetHttpProxyHostname("www.my-http-proxy.com")
    mailman.SetHttpProxyPort(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.SetMailHost("pop.someMailServer.com")

    // Set the POP3 login/password.
    mailman.SetPopUsername("myLogin")
    mailman.SetPopPassword("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.
    bundle := mailman.CopyMail()
    if mailman.LastMethodSuccess() == false {
        fmt.Println(mailman.LastErrorText())
        mailman.DisposeMailMan()
        return
    }

    i := 0
    // email is a Email
    for i < bundle.MessageCount() {
        email := bundle.GetEmail(i)
        fmt.Println("From: ", email.From())
        fmt.Println("Subject: ", email.Subject())
        email.DisposeEmail()
        i = i + 1
    }

    bundle.DisposeEmailBundle()

    success := mailman.Pop3EndSession()

    mailman.DisposeMailMan()
