//  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:

//  of the SOCKS proxy server:

//  SOCKS5 servers support full login/password authentication.

//  Set the POP3 server's hostname

//  Set the POP3 login/password.
