spam filtering software for exchange 2007

[sonoma1993]

I'm looking for some spam filtering software for my home exchange 2007 server? what do you guys recommend to use? Currently i've been running a trial version of GFI mail defense. It works good for the most part. Any free sollutions out there?

Here is a comparison of some:

You can also look at offloading the filtering somewhere else:

There are some steps that can be taken just using Exchange itself:

There are not many free solutions out there. An alternative is if you have an extra machine, you can install multiple versions of linux on it and set up something like spamassassin or use untangle.
