Swift Requires Chilkat v11.0.0+

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

    //  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.
    let mailman = CkoMailMan()!

    //  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.
    let bundle = CkoEmailBundle()!
    var keepOnServer: Bool = true
    var headersOnly: Bool = false
    //  Irrelevent because we are NOT downloading headers-only
    var numBodyLines: Int = 0
    success = mailman.fetchAll(keepOnServer: keepOnServer, headersOnly: headersOnly, numBodyLines: numBodyLines, bundle: bundle)
    if success == false {
