SMTP using SOCKS5, SOCKS4 Proxy

Demonstrates how to communicate with an SMTP server via a SOCKS4 or SOCKS5 proxy. PowerBuilder

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The mailman object is used for sending and receiving email.

// To use a SOCKS4 or SOCKS5 proxy, simply set the following
// properties prior to making any calls that communicate with
// an SMTP server:
// The SOCKS hostname may be a domain name or 
// IP address:
loo_Mailman.SocksHostname = "www.mysocksproxyserver.com"
loo_Mailman.SocksPort = 1080
loo_Mailman.SocksUsername = "myProxyLogin"
loo_Mailman.SocksPassword = "myProxyPassword"
// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
loo_Mailman.SocksVersion = 5
// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.

// Set the SMTP server.
loo_Mailman.SmtpHost = "smtp.chilkatsoft.com"

// Set the SMTP login/password (if required)
loo_Mailman.SmtpUsername = "myUsername"
loo_Mailman.SmtpPassword = "myPassword"

// Create a new email object

// Call SendEmail to connect to the SMTP server and send.
// The connection (i.e. session) to the SMTP server remains
// open so that subsequent SendEmail calls may use the
// same connection.

    destroy loo_Email

// Some SMTP servers do not actually send the email until 
// the connection is closed.  In these cases, it is necessary to
// call CloseSmtpConnection for the mail to be  sent.  
// Most SMTP servers send the email immediately, and it is 
// not required to close the connection.  We'll close it here
// for the example:
li_Success = loo_Mailman.CloseSmtpConnection()
if li_Success <> 1 then
