This may be off the wall for this mailing list but it's the information I'm lacking to deploy qmail. It also seems to be the least referenced item on the net. Deploying qmail as an alternative to the traditional Novell or Microsoft solutions what tools are available to centrally create and manage global address books for company networks. Specifically: 1. What common global address book administration programs are being used, including ones compatible with Outlook clients. 2. Are there any that integrate with the Unix/Linux user creation to reduce administration (using scripts or program interface). 3. Use alias names for local network deliveries. 4. Allow simple creation of distribution lists by the administrator with internal and external addresses. I'd appreciate pointers to any programs, books, or references that are available. thanks d. divine
