I have implemented Exchange Server 2003 in cluster configuration. All outgoing and incoming email is sent through an anti spam Server which does all the filtering. How ever, this server is being hammered and is becoming overload. I’d like to implement a second anti-spam server and I’d like to do some load balance. What I mean is that I want exchange virtual server to send mail trough anti-spam1 and anti-spam2, and in case any of the filters goes down, the other server can take the entire load.
If you have any suggest to do that, I’d appreciate it.
