CentOS6.4安装EMOS1.6邮件系统1 安装前的准备工作1.1 关闭selinux1、临时关闭（不用重启机器）：#setenforce 0 #设置SELinux 成为permissive模式 #setenforce 1 设置SELinux 成为enforcing模式2、修改配置文件需要重启机器：vi /etc/selinux/config将SELINUX=enforcing改为SELINUX=disabled重启机器即可3、查看selinux状态：#/usr/sbin/sestatus -v #如果SELinux status参数为enabled即为开启状态SELinux status: enabled1.2 yum先安装好以下组件:#yum -y install createrepo 制作yum仓库文件工具#yum -y install httpd #yum -y install mysql mysql-server mysql-devel 安装mysql数据库支持Extmail#groupadd -g 1000 vgroup 配置好邮件虚拟组和用户#useradd -u 1000 -g 1000 -M vuser1.下载EMOS镜像# su - root# mkdir /path# cd /path#wget http:/210.21.119.141/EMOS_1.6_x86_64.iso制作本地yum仓库# mkdir /mnt/EMOS# mount -o loop /path/EMOS_1.6_x86_64.iso /mnt/EMOS 装载ios镜像文件至EMOS目录# cd /mnt# createrepo . 创建yum源配置文件# cd /etc/yum.repos.d# mkdir backup# mv *.repo ./backup# vi EMOS.repo加入以下内容EMOSname=EMOSbaseurl=file:/mnt/enabled=1gpgcheck=0# yum clean all# yum list2 配置MTApostfix2.1 检查postfix CenOS6.4默认安装了postfix,并且可以支持mysql了，所以不用再安装了#rpm -qa |grep postfix postfix-2.6.6-2.2.el6_1.x86_642.2 配置postfix# postconf -n /etc/postfix/main2.cf# mv /etc/postfix/main.cf /etc/postfix/main.cf.bak# mv /etc/postfix/main2.cf /etc/postfix/main.cf# vi /etc/postfix/main.cf #修改main.cf 配置文件增加以下内容# hostnamemynetworks = 127.0.0.1myhostname = mail.extmail.orgmydestination = $mynetworks $myhostname# bannermail_name = Postfix - by extmail.orgsmtpd_banner = $myhostname ESMTP $mail_name# response immediatelysmtpd_error_sleep_time = 0s# Message and return code controlmessage_size_limit = 5242880mailbox_size_limit = 5242880show_user_unknown_table_name = no# Queue lifetime controlbounce_queue_lifetime = 1dmaximal_queue_lifetime = 1d2.3 设置postfix开机自启# chkconfig postfix on3 配置courier-authlib3.1 安装courier-authlib# yum install courier-authlib courier-authlib-mysql3.2 修改authlib 配置文件# rm -f /etc/authlib/authmysqlrc# vi /etc/authlib/authmysqlrcMYSQL_SERVER localhostMYSQL_USERNAME extmailMYSQL_PASSWORD extmailMYSQL_SOCKET /var/lib/mysql/mysql.sockMYSQL_PORT 3306MYSQL_OPT 0MYSQL_DATABASE extmailMYSQL_USER_TABLE mailboxMYSQL_CRYPT_PWFIELD passwordMYSQL_UID_FIELD uidnumberMYSQL_GID_FIELD gidnumberMYSQL_LOGIN_FIELD usernameMYSQL_HOME_FIELD homedirMYSQL_NAME_FIELD nameMYSQL_MAILDIR_FIELD maildirMYSQL_QUOTA_FIELD quotaMYSQL_SELECT_CLAUSE SELECT username,password,uidnumber,gidnumber, CONCAT(/home/domains/,homedir), CONCAT(/home/domains/,maildir), quota, name FROM mailbox WHERE username = $(local_part)$(domain)3.3 修改authmysqlrc 的权限和拥有者# chown daemon.daemon /etc/authlib/authmysqlrc# chmod 660 /etc/authlib/authmysqlrc3.4 修改authdaemonrc # vi /etc/authlib/authdaemonrcauthmodulelist=authmysqlauthmodulelistorig=authmysql3.5 启动courier-authlib# service courier-authlib startStarting Courier authentication services: authdaemond3.6 修改authdaemon socket 目录权限，否则以下面的测试SMTP认证就不能通过# chmod 755 /var/spool/authdaemon/4 配置maildrop4.1 安装maildrop# yum install maildrop4.2 配置maildrop配置master.cf 为了使Postfix支持Maildrop，必须修改/etc/postfix/master.cf文件，注释掉原来的maildrop的配置内容，并改为：# vi /etc/postfix/master.cfmaildrop unix - n n - - pipe flags=DRhu user=vuser argv=maildrop -w 90 -d $user$nexthop $recipient $user $extension nexthop注意：flags前面有“两个空格”配置main.cf 由于maildrop不支持一次接收多个收件人，因此必须在/etc/postfix/main.cf里增加如下参数：# vi /etc/postfix/main.cfmaildrop_destination_recipient_limit = 14.3 测试maildrop对authlib支持#maildrop vmaildrop 2.0.4 Copyright 1998-2005 Double Precision, Inc.
