SMTP using SOCKS5, SOCKS4 Proxy

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

LOCAL lnSuccess
LOCAL loMailman
LOCAL loEmail

lnSuccess = 0

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

*  Set the SMTP server.
loMailman.SmtpHost = "smtp.chilkatsoft.com"

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

*  Create a new email object
loEmail = CreateObject('Chilkat.Email')

loEmail.Subject = "This is a test"
loEmail.Body = "This is a test"
loEmail.From = "Chilkat Support <support@chilkatsoft.com>"
lnSuccess = loEmail.AddTo("Chilkat Admin","admin@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.  
lnSuccess = loMailman.SendEmail(loEmail)
IF (lnSuccess <> 1) THEN
    ? loMailman.LastErrorText
    RELEASE loMailman
    RELEASE loEmail
    CANCEL
ENDIF

*  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:
lnSuccess = loMailman.CloseSmtpConnection()
IF (lnSuccess <> 1) THEN
    ? "Connection to SMTP server not closed cleanly."
ENDIF

? "Mail Sent!"
