Typical moron PHBs :) Maybe they are looking for a SBS/Ex/SCE book? Your market is individual system administrators and trainers, NOT a business or its management! What are they even thinking; a small business usually can't even afford a full time sysadmin let alone a training budget!? I would say a better approach is by topic but with relevant notes that cover the various size installations. For example, at a small installation (w/no full time sysadmin) it's probably best to have all the external mail go through a managed service such as postini. Obviously this becomes prohibitively expensive and inflexible at larger sites. Sizes at perhaps this many users: <20 w/no admin, 50-500/1000 w/full time staff wearing many hats, >500/1000 w/dedicated messaging personnel. Time to find a different publisher? ~JasonG -- ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
