// The mailman object is used for receiving (POP3) 
// and sending (SMTP) email.
Chilkat.MailMan mailman = 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.someMailServer.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.
Chilkat.EmailBundle bundle = new Chilkat.EmailBundle();
bool keepOnServer = true;
bool headersOnly = false;
// Irrelevent because we are NOT downloading headers-only
