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

'  Set the SMTP server (obviously, use your SMTP server, not chilkatsoft.com)
mailman.SmtpHost = "smtp.chilkatsoft.com"

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

'  Create a new email object
set email = Server.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")
'  To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

'  To send high-priority email, 
'  add the X-Priority header field with the value "1" 
'  to indicate highest-priority.
'  A value of "3" is normal, which is the same as not setting
'  the X-Priority header at all, and "5" is the lowest. 
'  "2" and "4" are in-betweens.

'  Microsoft Outlook might add the following headers when
'  sending high-priority email.

'  X-Priority: 1 (Highest) 
'  X-MSMail-Priority: High 
'  Importance: High 

'  The X-Priority header alone is enough to make the email high-priority.

email.AddHeaderField "X-Priority","1"

'  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.  
success = mailman.SendEmail(email)

    Response.Write "<pre>" & Server.HTMLEncode( mailman.LastErrorText) & "</pre>"
