' 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")
set mailman = CreateObject("Chilkat.MailMan")

' 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.
mailman.HttpProxyHostname = "www.my-http-proxy.com"
mailman.HttpProxyPort = 3128

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

' Set the SMTP server.
mailman.SmtpHost = "smtp.chilkatsoft.com"

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

' Create a new email object
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Email")
set email = CreateObject("Chilkat.Email")

email.Subject = "This is a test"
email.Body = "This is a test"
email.From = "Chilkat Support <support@chilkatsoft.com>"
success = email.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.  
success = mailman.SendEmail(email)
If (success <> 1) Then
    outFile.WriteLine(mailman.LastErrorText)
    WScript.Quit
End If

' 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:
success = mailman.CloseSmtpConnection()
If (success <> 1) Then
    outFile.WriteLine("Connection to SMTP server not closed cleanly.")
End If

outFile.WriteLine("Mail Sent!")

outFile.Close
