Our research group has developed new, stateof-the-art antispam software, described in other papers. We are in the process of deploying that software in a large production corporate infrastructure, as a replacement for the prior antispam solution. This paper describes how we went about the deployment, and our experiences therewith, with an eye toward pointing out the icebergs and the lifeboats, to help make the process go smoothly for others. We also report what we learned, in the process, about user needs and expectations with respect to antispam solutions.
