一、前言
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。
二、环境
1.系统环境

三、流程分析
四、具体配置
1.安装apache和mysql
# yum install httpd mysql mysql-server mysql-devel
openssl-devel dovecot perl-DBD-MySQL
tcl tcl-devel libart_lgpl
libart_lgpl-devel libtool-ltdl libtool-ltdl-devel expect
# service mysqld start
# mysqladmin -u root -p password '123'
2.卸载postfix RPM包，创建postfix和postdrop用户
# cp /etc/init.d/postfix /etc/init.d/postfix.bak # yum remove postfix # id postfix uid=89(postfix) gid=89(postfix) groups=89(postfix),12(mail) # groupdel postfix groupdel: cannot remove the primary group of user 'postfix' # userdel -r postfix userdel: /var/spool/postfix not owned by postfix, not removing # groupdel postfix groupdel: group 'postfix' does not exist # userdel -r postfix userdel: user 'postfix' does not exist # groupadd -g 2525 -r postfix # useradd -g postfix -u 2525 -s /sbin/nologin -M postfix # groupdel postdrop # userdel -r postdrop userdel: user 'postdrop' does not exist # groupadd -g 2526 -r postdrop # useradd -g postdrop -u 2526 -s /sbin/nologin -M postdrop # id postfix uid=2525(postfix) gid=2525(postfix) groups=2525(postfix) # id postdrop uid=2526(postdrop) gid=2526(postdrop) groups=2526(postdrop)
3.安装postfix
# tar -zxvf postfix-2.8.2.tar.gz -C /usr/local/src/ # cd /usr/local/src/postfix-2.8.2/ # make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/include/sasl -DUSE_TLS' 'AUXLIBS=-L/usr/lib/mysql -lmysqlclient -lz -lm -L/usr/lib/sasl2 -lsasl2 -lssl -lcrypto' # make # make install
[]号中的是缺省值，”]”后的是输入值，省略的表示采用默认值。
