We are setting up a new 2003 exchange environment and are going to be useing a model that includes a smart host to do all our email handeling from the internet. I am wondering what everyone's advise is on antivirus and spam filtering for that box. Our thought was to put symantec corporate on that box with some type of spyware filter and have that run all the time. Then just install the exchage option on the exchange servers as a added percaution. Does this sound about right or would there be a better way to do this? Thanks for the advise!
