*  The mailman object is used for sending and receiving email.
loMailman = CreateObject('Chilkat.MailMan2')

*  Any string argument automatically begins the 30-day trial.

lnSuccess = loMailman.UnlockComponent("30-day trial")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX("Component unlock failed")
    QUIT
ENDIF

*  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.
loMailman.HttpProxyHostname = "www.my-http-proxy.com"
loMailman.HttpProxyPort = 3128

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

*  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.Email2')

loEmail.Subject = "This is a test"
loEmail.Body = "This is a test"
loEmail.From = "Chilkat Support <support@chilkatsoft.com>"
loEmail.AddTo("Chilkat Admin","admin@chilkatsoft.com")

*  Call SendEmail to connect to the SMTP server via the HTTP proxy 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
    =MESSAGEBOX(loMailman.LastErrorText)
    QUIT
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
    =MESSAGEBOX("Connection to SMTP server not closed cleanly.")
ENDIF

=MESSAGEBOX("Mail Sent!")
