//  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.

//  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:
CkMailMan_putSocksHostname(mailman,'www.mysocksproxyserver.com');
CkMailMan_putSocksPort(mailman,1080);
CkMailMan_putSocksUsername(mailman,'myProxyLogin');
CkMailMan_putSocksPassword(mailman,'myProxyPassword');
//  Set the SOCKS version to 4 or 5 based on the version
//  of the SOCKS proxy server:
CkMailMan_putSocksVersion(mailman,5);
//  Note: SOCKS4 servers only support usernames without passwords.
//  SOCKS5 servers support full login/password authentication.

//  Set the POP3 server's hostname
CkMailMan_putMailHost(mailman,'pop.example.com');

//  Set the POP3 login/password.
CkMailMan_putPopUsername(mailman,'myLogin');
CkMailMan_putPopPassword(mailman,'myPassword');

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