  // To use a SOCKS4 or SOCKS5 proxy, simply set the following

  // a POP3 server:
  // The SOCKS hostname may be a domain name or 
  // IP address:
  mailman.socksHostname = 'www.mysocksproxyserver.com';

  // 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

  // Set the POP3 login/password.
