以下配置在zimbra8.5中测试，未在其他版本中测试过，不能保证是否有效。
安装如下：
系统环境：CentOS 6.5 x86_64
Zimbra版本：zimbra 8.5.0
1.zimbra官网：http://www.zimbra.com/ 进入官网下载开源版本，
我此时下载的为http://files2.zimbra.com/downloads/8.5.0_GA/zcs-8.5.0_GA_3042.RHEL6_64.20140828192005.tgz
2.zimbra不支持32位系统安装，请使用64为系统；
3.zimbra在安装时要检测MX，所以要在之前配置好dns MX解析；
4.安装会安装到/opt目录，请确保/opt目录由足够空间
安装前：
1.关闭selinux，编辑/etc/selinux/config
SELINUX=disabled
2.开放防火墙端口，编辑/etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 7071 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8087 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8443 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 110 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 143 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 993 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 995 -j ACCEPT
3.配置主机名，编辑/etc/sysconfig/network
HOSTNAME=mail.domain.com
4.配置hosts，编辑/etc/hosts
10.172.250.121 mail.domain.com
5.关闭sendmail或postfix服务，避免25端口被占用
/etc/init.d/sendmail stop
chkconfig sendmail off
/etc/init.d/postfix stop
chkconfig postfix off
6.重启服务器，确保所有配置生效
# reboot
一、安装dnsmasq
1.安装dnsmasq
# yum install dnsmasq bind-utils
2.配置dnsmasq
# cp /etc/dnsmasq.conf /etc/dnsmasq.conf.bak
添加以下到/etc/dnsmasq.conf
no-resolv
server=127.0.0.1
domain=domain.com
mx-host=domain.com,mail.domain.com,5
添加以下到/etc/resolv.conf
nameserver 127.0.0.1
启动dnsmasq
# /etc/init.d/dnsmasq start
测试：
[root@mail ~]# dig domian.com MX
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.23.rc1.el6_5.1 <<>> domain.com MX
;; global options: +cmd

[root@mail ~]#
测试成功。
二、安装zimbra
1.解压
# tar -zxvf zcs-8.5.0_GA_3042.RHEL6_64.20140828192005.tgz
# cd zcs-8.5.0_GA_3042.RHEL6_64.20140828192005
2.运行安装脚本
# ./install.sh

一、反垃圾病毒邮件配置
1.增加权值
在文件/opt/zimbra/conf/amavisd.conf.in中找到# read_hash("/var/amavis/sender_scores_sitewide"),部分，大概在340行左右，将你要信任或不信任的域或邮箱名按照格式填入下面，赋予合适的分值,分值越大表示不信任，分值越小表示信任(可理解为-10.0为信任，+10.0为阻断)。
如：我需要信任123@abc这个邮箱，可以这样添加
'123@abc.com' => -10.0, (不要忘了后面的逗号，将其分值减少增加被信任的机率)
如：我不信任333@bbb.com这个邮箱，可以这样添加
'333@bbb.com' => +10.0, (不要忘了后面的逗号,将其分值增加就会判为垃圾邮件)
重启服务：
[zimbra@mail ~]$ zmamavisdctl reload
2.添加黑白名单
在文件/opt/zimbra/conf/amavisd.conf.in末尾添加以下：
read_hash(%whitelist_sender,'/opt/zimbra/conf/whitelist');
read_hash(%blacklist_sender,'/opt/zimbra/conf/blacklist');
创建黑白名单文件：
# touch /opt/zimbra/conf/{whitelist,blacklist}
授予拥有者为zimbra用户：
# chown zimbra /opt/zimbra/conf/whitelist
# chown zimbra /opt/zimbra/conf/blacklist
分别在文件中添加你需要设为白名单或黑名单的邮箱名或域名（一行一个），如：
# cat /opt/zimbra/conf/whitelist
gmail.com
111@abc.com
# cat /opt/zimbra/conf/blacklist
currantcantaloupechef.com
musicroyalties.net
mapleleafmail.com
重启服务：
[zimbra@mail ~]$ zmamavisdctl reload
3.使用RBL列表
可使用中国反垃圾邮件联盟（http://www.anti-spam.org.cn/ ）的RBL，在邮件管理后台 主页--配置--全局设置--MTA 的RBL列表项中填入 cblless.anti-spam.org.cn 然后保存。
查看/opt/zimbra/postfix/conf/main.cf文件中的smtpd_recipient_restrictions项有没有 reject_rbl_client cblless.anti-spam.org.cn 这个内容，如果没有的话说明还没生效，在root用户下执行/opt/zimbra/postfix/sbin/postfix reload
说明：
我遇到的情况：使用此方法确实能阻断掉许多垃圾邮件，但使用我的gmail邮箱给我发送的时候也被阻断了，目前没有找到解决办法，阻断的日志内容如下：
Nov 30 00:06:16 mail postfix/smtpd[13458]: connect from mail-ie0-f175.google.com[209.85.223.175]

4.关键字过滤
在/opt/zimbra/data/spamassassin/localrules/目录下新建规则文件custom_spam_rules.cf
可在网上找其他组织已经做好的规则文件，如http://www.ccert.edu.cn/spam/sa/Chinese_rules.cf（此链接已失效）
内容如下：
加入你要过滤的关键字（中文或英文都行），第1行表示主题为“my new photo”,第2行表示描述主题中包含“my new photo”，第3行表示遇到这类的邮件则为这封邮件加20分（就直接判断为垃圾邮件给删除了），如果不想被直接删除，建议分值设低点，也避免误判，我这里是已经确定这样的为垃圾邮件就这样设了。
还有注意文中的CN_SUBJECT_1，CN_SUBJECT_2，CN_SUBJECT_3，CN_SUBJECT_4 ... 如需要继续设置则按此规则设置，我最开始没注意直接拷贝添加新的规则，结果只有最后一组规则生效，原因就是因为这个没修改。
header CN_SUBJECT_1 Subject =~ /my new photo/
describe CN_SUBJECT_1 Subject contains "my new photo"
score CN_SUBJECT_1 20.0
header CN_SUBJECT_2 Subject =~ /my photo/
describe CN_SUBJECT_2 Subject contains "my photo"
score CN_SUBJECT_2 20.0
header CN_SUBJECT_3 Subject =~ /my icc/
describe CN_SUBJECT_3 Subject contains "my icc"
score CN_SUBJECT_3 20.0
header CN_SUBJECT_4 Subject =~ /优惠/
describe CN_SUBJECT_4 Subject contains "优惠"
score CN_SUBJECT_4 1.523
header CN_SUBJECT_5 Subject =~ /发票/
describe CN_SUBJECT_5 Subject contains "发票"
score CN_SUBJECT_5 1.324
