I have Zimbra fully operational on Debian 4.0 Etch Stable 32BIT,

Here some of the changes made to make it work.

# editor /etc/debian_version to 3.1 from 4.0

# apt-get install sudo curl fetchmail libgmp3c2 libssl0.9.7 libdb3 libxml2 perl libexpat1 libpcre3 file

# editor /utils/utilfunc.sh and change script to look for libgmp3c2 not libgmp3

After install is complete run the below command for https web access;

# su - zimbra zmtlsctl https to enable https webmail

add host ip of zimbra server 192.168.0.XXX to ipcop or DNS server (inbound mail did not work with out this) there are other way to get around this

Than configure using web admin access.

I must say i have work with MS exchange for many years and Zimbra is really to my liking, and Exchange 2007 will use 2GB of ram with all components installed i run Zimbra on a vmware server with 256mb! which only uses 1 to 2% cpu use - PC is E6300 duo core running at 2.6ghz.
