Finally got Zimbra working on Debian
Myself and a friend managed to get Zimbra working on a Debian etch/sid distro by building rpms and then converting to debs. We managed to document the steps and incorporate some of the changes to the install.sh script.
We took the easy way out without recompiling the packages or using native debs so this could break some other native apps. Use at your own risk! We also tested this witout the SpamAssasin/ClamAV pieces by saying N to that question.
Inststructions are in the attachment.
