Yes, one recommendation for sure. Give up on your first goal. It'll never happen, because fighting spam is an arms race, with new tactics needing to be adopted. As for the second goal, spamassassin along with one of several packages will do well for you - I use Maia Mailguard, but I've heard good things about MailZu with Amavisd-new as well. Others will talk about other packages. It's worth taking a look at each of them to figure out what works for you. Kurt
