Best client side spam filter?

[daztrouk]

A company provide us with email filtering, but spam still seeps through every so often. We previously used Spam Bayes, but it seems to have gone **** up for some reason. Can anyone recommend a good spam filter that can be used on MS Outlook?

The one bundled in with ESET SmartSecurity (aka NOD32 antivirus)

i should have been more specific. I don't need a security suite, just a standalond application.

spamihilator seems to only work with pop3 accounts, whereas i'm in an exchange environment. I've got Spamfighter installed now, so we'll see how that goes.
