Hi We'd like to be able to restrict posting to a list based on IP address/domain name. The list is Send= Public but we want to restrict the ability to post to local IP addresses only. Can this be done using the "Service" keyword? My hunt through the documentation seemed to indicate that the Service keyword was only to be used for subscription requests. If there is a way to do this other than the Service= keyword Thanks Scotty -- Steve Howie Campus Services, CCS University of Guelph
