We had a mail server crash that was running Ubuntu Dapper with Zimbra 4.5.6-1044. I've got the entire /opt/zimbra folder backed up, and was ready to follow instructions that are on wiki. The community edition or open source installers don't go back that far.
We've since switched to a hosted Zimbra, but I would like to still have this data available to us. What are my options? Where do I get the older versions. I looked in the subversion web viewer that was linked but did not see the ubuntu binaries.
