安装
zimbra 当前稳定版本是 4.5，并没有 for debian etch 的二进制包，好在有提供
for debian sarge 的，安装的话需要做一些小手脚：
// quote from http://www.zimbra.com/forums/installation/6443-debian-etch-4-0-install.html#post41225
before you start, *setup your DNS*. Zimbra install is very sensitive to correct DNS setup, particularly /etc/hosts and forward resolution of the hostname you are installing on as returned from hostname. Search wiki/forum for correct DNS setup.
change /etc/debian_version to 3.1
apt-get install sudo curl fetchmail libgmp3c2 libssl0.9.7 libdb3
chmod a+rwx /tmp
tar -xzf
cd zcs/
clean out previous attempts:
sh install -u
rm -rf /opt/zimbra
rm /tmp/install*
rm /tmp/zmsetup*
rm /tmp/*zim*
change util/utilfunc.sh
if [ $PLATFORM = "UBUNTU6"]; then
to
if [ $PLATFORM = "UBUNTU6" -o $PLATFORM = "DEBIAN3.1" ]; then
sh install.sh
Strangely detects hostname as domainname (never quite understood why it does this). Select 'Yes' for "Change domain name", change to domainname "domain.com" instead of "host.domain.com"
If you haven't set your MX yet, ignore (you'll need to set this later but its fine for install):
DNS ERROR - none of the MX records for ijichi.org
resolve to this host
It is suggested that the MX record resolve to this host
Re-Enter domain name? [Yes]
^^ Choose "No"
Install Menu: Choose 6 for zimbra-store, 4 for Admin Password, enter password, 'r' or for previous menu, 'a' to apply, Enter for next two questions:
Save configuration data to a file? [Yes]
Save config in file: [/opt/zimbra/config.15938]
Then 'Yes' for: The system will be modified - continue? [No] yes
Checkout output carefully for *any* errors, should install fine.
You can change /etc/debian_version back to 4.0 after install but you'll have to change it for each upgrade
上面所说还是有一些不符的地方，安装脚本名称为 ./install.sh，修改过后按照法安装顺利。
安装之前需要注意端口冲突，先停掉如 apache 等可能端口冲突的程序。
调整
zimbra 提供的包是完整的环境，包括 apache, tomcat, mysql 等。如果系统已经有了 apache 需要做一些调整。如果原有的 web 不需要 https 的支持，完全可以让 zimbra apache 跑在 443，既提高了安全性，又不会和以后系统冲突。

zmtlsctl https
tomcat restart
so far so good，直到
问题
实际运行中发现 smtp 无法认证，搜索了一下，发现是认证 URL 没有正确设置到 https 导致，属于 zimbra 4.5 的 BUG。重新设置 zimbraMtaAuthHost 手工修正此问题。
