I have noticed that at work we started using the baracuda networks spam firewall and since then we have had far fewer issues with spam. I used to get spam on an email address I didn’t even know people knew about. I don’t know how spammers find out these things. But a hard working Spam Filter that works like this has made all the difference. And her’s a cool image of an email server I found on their site. Somehow we always knew the answer to spam was going to be a fish.
