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

//  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.
oMailman := CreateObject("Chilkat.MailMan")

//  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:
oMailman:SocksHostname := "www.mysocksproxyserver.com"
oMailman:SocksPort := 1080
oMailman:SocksUsername := "myProxyLogin"
oMailman:SocksPassword := "myProxyPassword"
//  Set the SOCKS version to 4 or 5 based on the version
//  of the SOCKS proxy server:
oMailman:SocksVersion := 5
//  Note: SOCKS4 servers only support usernames without passwords.
//  SOCKS5 servers support full login/password authentication.

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

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

//  Create a new email object
oEmail := CreateObject("Chilkat.Email")

oEmail:Subject := "This is a test"
oEmail:Body := "This is a test"
oEmail:From := "Chilkat Support <support@chilkatsoft.com>"

//  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.  
nSuccess := oMailman:SendEmail(oEmail)

//  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:
nSuccess := oMailman:CloseSmtpConnection()
IF (nSuccess != 1)
