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

lcOauth2_access_token = "some_previously_obtained_token"

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

* Set the properties for the SMTP server, whatever they may be..
loMailman.SmtpHost = "smtp.example.com"
loMailman.SmtpPort = 587
loMailman.StartTLS = 1

loMailman.SmtpUsername = "myLogin"
loMailman.OAuth2AccessToken = lcOauth2_access_token

* 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 Example <joe@example.com>"
loEmail.AddTo("Chilkat Admin","admin@chilkatsoft.com")

* Connect to the server indicated by the SmtpHost property
lnSuccess = loMailman.SmtpConnect()
IF (lnSuccess <> 1) THEN
    ? loMailman.LastErrorText
    RELEASE loMailman
    RELEASE loEmail
