University MailScanner Setup

I'm posing a question to those of you who work for a University or College.

Here at Emory, we have a hosted email filtering called Postini (which is now owned by Google). Behind that, we have six MailScanner machines that relay mail to the appropriate internal mail system. After the economic turndown, we have been looking anywhere to save costs. I'm contemplating proposing that we dump our hosted filtering solution because it is quite expensive ($5+ per user per year), and rely on MailScanner instead entirely. Then we would just have a bunch of MailScanner machines fronted by a load balancer to handle all inbound email (I'd imagine we need more than six after doing so)

I'm wondering though how other colleges are handling their mail filtering using MailScanner. How many machines are being used, etc, etc?

We currently get about 30-40 million email messages per week, of which about 1.5 million are delivered to our relays. We have approximately 40,000 email accounts.

Thanks for any assistance, advice.
