Boring tecchie stuff

Next week I'm going to installing Zimbra as a mail/calendar sharer for work, hopefully I'll get around to posting the results here. The web demos look good so we'll soon see how easy it is to manage! Any experiences that others have had - web searches seem to suggest pretty positive results. Manlug had a talk on Saturday about Meldware which seems to cover pretty similar ground but I was a little tied up on Saturday! Any Meldware experiences?
