Hi Betty,
As Mike has suggested, the popular means to prevent spam(machine generated
post ) is through some image based validation(the captcha as Mike mentioned)
http://recaptcha.net/captcha.html
in classic ASP pages, you may need to write a COM component(via VB ) which
can programmtically generate some image(that display some digits) and let
the user input those digits as validation code. The server-side can compare
the validation code with the server cache(in session) to ensure the request
is post by human interactively rather than machine generated code.
Here are some reference about such validation in classic ASP:

Hi all,
We have many forms on our site that users can fill out and ask questions,
request information etc. but somehow, we receive a lot of junk mails (more
than two hundreds) within two weeks through these forms.
I don't know hot to stop these junk emails.
Can you provide some ideas and ways to implement?
thank you so much.
