Extmail 是一个以perl语言编写，面向大容量/ISP级应用，免费的高性能Webmail软件，主要包括ExtMail、Extman两个部分的程序套件。ExtMail套件用于提供从浏览器中登录、使用邮件系统的Web操作界面，而Extman套件用于提供从浏览器中管理邮件系统的Web操作界面。它以GPL版权释出，设计初衷是希望设计一个适应当前高速发展的IT应用环境，满足用户多变的需求，能快速进行开发、改进和升级，适应能力强的webmail系统。
extmail，这个基于linux的webmail软件，我今天也在虚拟机里测试了一番，由于计算机的性能实在不佳，导致编译什么的耗时严重，到最后，甚至影响了我的心情，在本次部署的尾声，加上和朋友的交流过程中，发现这套邮件体系，在中国能找到的资料和能得到的支持是少之又少（算是个人见解）于是关于邮件带毒网关和后续的操作，我不打算继续研究了，另外，感谢博主斩月和博主我为技术狂，前者的文章在我部署中解决了不少困惑，后者将我从混乱思路拯救出来！
部署具体步骤如下：
本环境基于Centos 6.2 LAMP架构。如果你需要我lamp架构的部署流程可以参考我的另一篇博文【图解】LAMP编译安装
1：使用验证库，可以使用mysql验证邮件账户
[root@chenyi1 phpMyadmin]# tar jxf /chenyi/courier-authlib-0.63.0.tar.bz2 -C /usr/src/
[root@chenyi1 phpMyadmin]# cd /usr/src/courier-authlib-0.63.0/
[root@chenyi1 courier-authlib-0.63.0]# groupadd postfix -g 1000
[root@chenyi1 courier-authlib-0.63.0]# groupadd vmail -g 1001
[root@chenyi1 courier-authlib-0.63.0]# groupadd postdrop -g 1002
[root@chenyi1 courier-authlib-0.63.0]# useradd -u 1001 -g 1000 vmail
[root@chenyi1 courier-authlib-0.63.0]# useradd -u 1000 -g 1000 postfix
[root@chenyi1 courier-authlib-0.63.0]# id vmail
查看相应的用户组关系
uid=1001(vmail) gid=1000(postfix) 组=1000(postfix)
[root@chenyi1 courier-authlib-0.63.0]# id postfix
uid=1000(postfix) gid=1000(postfix) 组=1000(postfix)
预配置
[root@chenyi1 courier-authlib-0.63.0]# ./configure --prefix=/usr/local/courier-authlib --with-mailuser=vmail --with-mailgroup=vmail --sysconfdir=/etc --without-authpam --without-authldap --without-authpwd --without-authshadow --without-authvchkpw --without-authpgsql --with-authmysql --with-mysql-libs=/usr/local/mysql/lib/mysql --with-mysql-includes=/usr/local/mysql/include/mysql --with-redhat --with-authmysqlrc=/etc/authmysqlrc --with-authdaemonrc=/etc/authdaemonrc CFLAGS="-march=i686 -O2 -fexpensive-optimizations" CXXFLAGS="-march=i686 -O2 -fexpensive-optimizations"
如果在配置过程中没有报错，那么即可编译、安装了。
[root@chenyi1 courier-authlib-0.63.0]# make && make install
更新动态链接库（后面类似操作，不予解释）
[root@chenyi1 courier-authlib-0.63.0]# echo '/usr/local/courier-authlib/lib/courier-authlib/' >> /etc/ld.so.conf
[root@chenyi1 courier-authlib-0.63.0]# ldconfig
注意：如果是64位系统，这里需要将i686修改为x86-64，关于各种编译选项的含义可以使用./configure --help 来获取
2：修改authlib库相关配置文件
[root@chenyi1 courier-authlib-0.63.0]# cp /etc/authdaemonrc.dist /etc/authdaemonrc
[root@chenyi1 courier-authlib-0.63.0]# grep -v '^#' /etc/authdaemonrc | grep -v '^$'
authmodulelist="authmysql" 被grep筛选后的有效配置
authmodulelistorig="authmysql"
daemons=5
authdaemonvar=/usr/local/courier-authlib/var/spool/authdaemon
DEBUG_LOGIN=0
DEFAULTOPTIONS=""
LOGGEROPTS=""
[root@chenyi1 courier-authlib-0.63.0]# cp /etc/authmysqlrc.dist /etc/authmysqlrc
[root@chenyi1 courier-authlib-0.63.0]# grep -v '^#' /etc/authmysqlrc | grep -v '^$'
MYSQL_SERVER 127.0.0.1
MYSQL_USERNAME extmail
MYSQL_PASSWORD itchenyi
MYSQL_SOCKET /tmp/mysql.sock
MYSQL_PORT 3306
MYSQL_OPT 0
MYSQL_DATABASE extmail
MYSQL_USER_TABLE mailbox
MYSQL_CRYPT_PWFIELD password
MYSQL_UID_FIELD 1001
MYSQL_GID_FIELD 1001
MYSQL_LOGIN_FIELD username
MYSQL_HOME_FIELD concat('/email/mailbox/',homedir)
MYSQL_NAME_FIELD name
MYSQL_MAILDIR_FIELD concat('/email/mailbox/',maildir)
3：启动authlib服务
[root@chenyi1 courier-authlib-0.63.0]# /usr/local/courier-authlib/sbin/authdaemond start
[root@chenyi1 courier-authlib-0.63.0]# ps -aux | grep courier

设置为开机启动
[root@chenyi1 courier-authlib-0.63.0]# echo '/usr/local/courier-authlib/sbin/authdaemond start' > /etc/rc.local
安装 cyrus-sasl,SASL (Simple Authentication Security Layer)简单认证安全层,功能主要是用于SMTP认证;而 Cyrus SASL是SASL的一个实现
1:卸载系统自带的sasl rpm包，使用--nodeps选项强制卸载
[root@chenyi1 courier-authlib-0.63.0]# rpm -qa | grep sasl
cyrus-sasl-plain-2.1.23-13.el6.i686
cyrus-sasl-devel-2.1.23-13.el6.i686
cyrus-sasl-lib-2.1.23-13.el6.i686
cyrus-sasl-md5-2.1.23-13.el6.i686
cyrus-sasl-2.1.23-13.el6.i686
[root@chenyi1 courier-authlib-0.63.0]# rpm -e $(rpm -qa | grep cyrus-sasl) --nodeps
[root@chenyi1 courier-authlib-0.63.0]# rpm -qa | grep sasl | wc -l
0
解包并进行预配置
[root@chenyi1 courier-authlib-0.63.0]# tar -zxf /chenyi/cyrus-sasl-2.1.22.tar.gz -C /usr/src/
[root@chenyi1 courier-authlib-0.63.0]# cd /usr/src/cyrus-sasl-2.1.22/

[root@chenyi1 cyrus-sasl-2.1.22]# ldconfig
编辑smtpd认证配置文件，此文件默认不存在
[root@chenyi1 cyrus-sasl-2.1.22]# vi /usr/local/sasl2/lib/sasl2/smtpd.conf 直接编辑该文件添加如下内容
pwcheck_method: authdaemond

[root@chenyi1 maildrop-2.5.4]# vi /etc/maildroprc 直接编辑添加该文件（默认没有这个文件）加入以下内容
logfile "/var/log/maildrop.log"
[root@chenyi1 maildrop-2.5.4]# touch /var/log/maildrop.log
[root@chenyi1 maildrop-2.5.4]# chown vmail:vmail /var/log/maildrop.log
配置postfix 支持 maildrop （大约在master.cf文件的67和68左右，你需要去掉相应的注释）
[root@chenyi1 maildrop-2.5.4]# grep -2 -i 'maildrop' /etc/postfix/master.cf |grep -v '^#'
maildrop unix - n n - - pipe
flags=DRhu user=vmail argv=/usr/local/bin/maildrop -d ${recipient}
[root@chenyi1 maildrop-2.5.4]# egrep '1001|maildrop' /etc/postfix/main.cf
virtual_uid_maps = static:1001
virtual_gid_maps = static:1001
virtual_transport = maildrop
配置Extman和Extmail等

配置slockd
[root@chenyi1 docs]# tar zxf /chenyi/slockd-0.99.tar.gz -C /usr/src/
[root@chenyi1 docs]# rm -rf /usr/src/slockd/
[root@chenyi1 docs]# tar zxf /chenyi/slockd-0.99.tar.gz -C /usr/local/
[root@chenyi1 docs]# /usr/local/slockd/slockd-init start
Starting spam locker daemon: slockd
[root@chenyi1 docs]# echo '/usr/local/slockd/slockd-init start' >> /etc/rc.local
[root@chenyi1 docs]# cd /var/run/
[root@chenyi1 run]# mkdir extmail
[root@chenyi1 run]# /var/www/html/extman/daemon/cmdserver -v -d
loaded ok
[root@chenyi1 run]# echo '/www/extman/daemon/cmdserver -v -d' >> /etc/rc.local
配置Apache
User vmail
Group vmail
在该配置文件末行加入
<VirtualHost *:80>
ServerName mail.itchenyi.com
DocumentRoot /www/extmail/html
ScriptAlias /extmail/cgi /www/extmail/cgi
Alias /extmail /www/extmail/html
ScriptAlias /extman/cgi /www/extman/cgi
Alias /extman /www/extman/html
<Directory /www>
Authtype basic
Options execcgi
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
到这里重启apache服务，你应该就可以使用默认的管理员帐号密码登录web了 extman默认管理帐号为：root@extmail.org 密码为：extmail*123*
另外，由于整个过程极为繁琐，在部署过程中也遇到很多错误，你可以参考我的另一片博文：Extmail排错篇
