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

* See Get Yahoo Mail OAuth2 Access Token for Desktop App 
* for sample code showing how to obtain a Yahoo Mail access token.

* In this example, our access token was previously saved to the following file which contains JSON like this:
* {
*   "access_token": "kCVQdnOdul...LHucA--",
*   "refresh_token": "AIenVXETSo0jklFBVkPS8vVm8E.Ej9ToRG.xDbDYmZ65WIs5t6CZhDrD",
*   "expires_in": 3600,
*   "token_type": "bearer",
*   "xoauth_yahoo_guid": "HGDQCVF5JB4YDOWHITQJFBHCWA"
* }

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
lnSuccess = loJson.LoadFile("qa_data/tokens/yahooMail.json")
IF (lnSuccess <> 1) THEN
    ? "Failed to load Yahoo access token file."
    RELEASE loJson
    CANCEL
ENDIF

lcAccessToken = loJson.StringOf("access_token")

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.MailMan')
loMailman = CreateObject('Chilkat.MailMan')

* Set the properties for the Yahoo SMTP server:
loMailman.SmtpHost = "smtp.mail.yahoo.com"
loMailman.SmtpPort = 465
loMailman.SmtpSsl = 1

* The SMTP username should be the Yahoo email address of the user's account that authorized your app to send email.
loMailman.SmtpUsername = "user@yahoo.com"
loMailman.OAuth2AccessToken = lcAccessToken

* 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 = "Joe User <user@yahoo.com>"
loEmail.AddTo("Chilkat Admin","admin@chilkatsoft.com")
* To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

* 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 loJson
    RELEASE loMailman
    RELEASE loEmail
    CANCEL
ENDIF

* You may close the connection here.  If the connection is kept open, 
* the next call to mailman.SendEmail will continue using the already-established connection
* (and automatically re-connect if needed).
lnSuccess = loMailman.CloseSmtpConnection()
IF (lnSuccess <> 1) THEN
    ? "Connection to SMTP server not closed cleanly."
