My website is written in classic ASP and I send out automatic emails when people join my mailing list. My hosting company uses Chilisauce ASP and is now requiring SMTP Authentication when I send the email. I currently use the CDONTS object but it does not support SMTP AUthentication. I have found examples like this:
Set objMessage = Server.CreateObject("CDO.Message")
but it doesn't look like ChiliSauce ASP supports the CDO object.
Unfortunately sun one asp does not support authentication (just double checked the manual and its not an option). The equivalent command is Server.CreateObject("CDONTS.NewMail"), the one you cite is the Microsoft version.
Sun One ASP was retired some months ago and there has been no active development/support for many years.
So I guess you'll have to go back to your isp, explain the situation, as they provide the infrastructure (including ASP) they will have to come up with a better solution. I guess they could allow unauthenticated access and restrict by ip address.
