How to temporarily disable a website and email for non-payment

I have a customer who has not responded to repeated requests for payment for web services. I host the site and the email. How do I temporarily disable both the easiest and most easily reversible way? I don't have access to the registrar account for the domain. I do realize his options. None are good for him, except to pay his bill.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

As you will have application hosted on your server, so create a web page and write comments "This site is temporarily stopped due to non-payment reason" or anything you want to comment. Then set home page redirection in customer's site to your page.

To stop mailing depends on which software/application you are using at backend. If you can provide a brief of application so we can find a way to this.

I would also zip all files in the root of the site and then delete them.  Depending on how the site is implemented, the user may still be able to get to pages by directly querying for them, for example aboutus.php, .html, etc.  By archiving all of the files and then deleting them, you're assured they will no longer be able to access the site.
