Neil,
As mentioned in a post below, a service based SPAM provider is the way to go. You keep the SPAM from even getting to your network modem/router/firewall. It does a great job and is easy to manage. One of the other benefits is it allows you to tighten down your SMTP traffic to only listen to a range defined by Postini instead of the entire world.
No updates or real management is necessary with Postini and you pay a little amount each month for an excellent service. They even have mail spooling so in the event your Internet connection goes down for an extended period of time, they will spool your mail for you and your customers don't get the dreaded undeliverables.
There are other services like this available, but Google recently purchased Postini and they only buy the best - LOL so that's a good idea of the quality of the product.
Hope this helps.

We also use a Barracuda spam filter as well as a Watchguard Firewall.
One big advantage of an appiance like Barracuda is that your Email filtering takes place OFF of your Email server thus reducing the load on your Exchange Server.
Actually our Watchguard catches nearly all of the SPAM and Virus' before it even gets to the Barracuda, but we like the 2 layers of defense.

Barracuda also comes with its own Virus Protector that stops 99% of virus contained in spam and e-mail from entering into Exchange. The tools contained in Barracuda give you control over all e-mail coming into your environment.
