We use Google Apps as our email service provider.
I would like to prevent a user from sending or receiving any new mail, while preserving this person's access to the archive of historical messages.
We are not currently using Postini.
Sending: I can't find anything myself.
Receiving: Using Email Delivery, I see that I can turn off all email delivery options so that no messages will be delivered. It seems, though, that this would fail silently, and I'd prefer to have an auto-responder up or to have the sender get a Not Deliverable notification.
Is there a way to do this?

You should be able to restrict inbound/outbound mail fairly simply. Under "Manage this domain" create a new organization under "Organization & Users". Name it "Restricted users" or some such.
Select the user account(s) you want to restrict. Select "Move to" and choose your new organization.
Under "Advanced tools" scroll down to "Restricted email delivery". Add the organization you just created and do not add any domains under the "Allowed" list. Any member of this organization will now be unable to send/receive new mail.
You can also limit the features of Google Apps (e.g. Docs, chat, Picasa, etc) using the same organization. Here is Google's documentation on the Restrict email delivery feature.
