dim themassage
set smail=Server.CreateObject(“CDONTS.NewMail”)
smail.to="liggyi@163.com"
'smail.from=“ppppll132@163.com
smail.Subject=“welcome”
themessage=“hello:”& chr(13) & chr(13) &“thanks for coming to our site!”& chr(13) & chr(13)_
&“”“We appreciate your business!”“”
smail.body=themessage
smail.importance=2
smail.send
set smail=nothing
response.write “done”
