// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// 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.
$mailman = new CkMailMan();

// 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->put_SocksHostname('www.mysocksproxyserver.com');
$mailman->put_SocksPort(1080);
$mailman->put_SocksUsername('myProxyLogin');
$mailman->put_SocksPassword('myProxyPassword');
// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
$mailman->put_SocksVersion(5);
// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.

// Set the POP3 server's hostname
$mailman->put_MailHost('pop.someMailServer.com');

// Set the POP3 login/password.
$mailman->put_PopUsername('myLogin');
$mailman->put_PopPassword('myPassword');

// Copy the all email from the user's POP3 mailbox 
// into a bundle object.  The email remains on the server.
// bundle is a CkEmailBundle
$bundle = $mailman->CopyMail();
