I am a network admin for a non profit organization that gets "free" email accounts from a local isp. Hence no local email server. I am looking for an appliance that can filter the spam from these "free" email accounts (pop). I know this is a pathetic situation.....much too complicated to explain the "politics" behind it here. Currently we have a watchguard firewall, but I am looking for something like the barracuda...if it would work in my current setup at this particular client. Thanks in advance
