ASPEmail problemer

Bruger den er kode:

    Set Mail = Server.CreateObject("Persits.MailSender")
    ' enter valid SMTP host
    Mail.Host = "localhost"
    Mail.Username = "user"
    Mail.Password = "pass"
   
    Mail.From = Request.form("email") ' From address
    Mail.FromName = Request.form("navn") ' optional
    Mail.AddAddress ""&rsMail("email")&""
   
    ' message subject
    Mail.Subject = Request.form("emne")
    ' message body
    Mail.Body = "Fra: "&Request.form("navn")&"<br />Emne: "&request.form("emne")&"<br />Body: "&Request.form("body")&"<br />"
    strErr = ""
    bSuccess = False
    On Error Resume Next ' catch errors
    Mail.Send ' send message
    If Err <> 0 Then ' error occurred
    strErr = Err.Description
    else
    bSuccess = True
    End If

og får denne fejl:
Error occurred: Software caused connect abort.
