// 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";

// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
mailman.SocksVersion = [NSNumber numberWithInt: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.

// Copy the all email from the user's POP3 mailbox 
// into a bundle object.  The email remains on the server.
