Good (hosted domain level) spam filters?

[Pepper]

Leaving my job where I had a barracuda spam firewall between the outside world and my home email server. Need a good filtering service for my domains, my connection isn't big enough to handle the spam traffic so it needs to be hosted somewhere. And it needs to be cheap or free. Four domains, around a dozen or so unique addresses.

Any suggestions? Anybody out there have a barracuda and willing to "adopt" me?

hmm. I am not sure about any hosting solutions that fit your needs, maybe DynDns email services. I have read good things on the Microsoft Online Services Exchange Hosted solution. Not bad pricing, but not free. Being MS, I am not sure if it works with non-exchange email servers.

I personally have a watchguard x550e at home and have been playing with Fortinet Fortiguards at work for clients, but those are hardware for in place setups and the Fortinets are more of UTM than just spam and obviously rely on a fatter pipe than what you say you have.
