LOCAL lnSuccess

* 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.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.MailMan')
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
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Email')
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!"
