Introduction This Report is intended as an accompanying volume to the E-mail Management Technology Management and Strategy Report published by Butler Group in June 2004. The original Report did not contain any Technology Audits or product comparisons. However, it did identify many vendor products in each of the e-mail management areas that were examined, namely: 1. Security Management. 2. Policy Management. 3. E-mail Archiving. 4. Knowledge Management and Collaboration. We believe that to implement a comprehensive e-mail management solution, functionality in the areas of security management, policy management, and e-mail archiving are essential. Most organisations will also require some form of Knowledge Management and Collaboration tools, but this functionality is not specific to e-mail management, and is likely to be part of a much wider solution, such as Enterprise Content Management (ECM).
