CkoImap *imap = [[CkoImap alloc] init];

//  To connect through an HTTP proxy, set the HttpProxyHostname
//  and HttpProxyPort properties to the hostname (or IP address)
//  and port of the HTTP proxy.  Typical port numbers used by
//  HTTP proxy servers are 3128 and 8080.
imap.HttpProxyHostname = @"www.myhttpproxy.com";
imap.HttpProxyPort = [NSNumber numberWithInt:3128];

//  Important:  Your HTTP proxy server must allow non-HTTP
//  traffic to pass.  Otherwise this does not work.

//  Connect to an IMAP server through the HTTP proxy.
//  Use TLS
