I've spent about a week working through the install on Ubuntu (w/ help from these forums and the wiki). Being that my host provider runs AMD64, I've built an install script to build a i386 chroot and install Zimbra (of course it should work for a i386 host too).
You can check it out here:
- server hostname resolves in DNS
- necessary ports are free
- I've been running this on a bare install so I'd be interested to know if there are conflicts with a real running host (i.e. MySQL on host and chroot)
Cheers and Thanks for the great software.
