邮件服务器Postfix

2014-03-20

一.邮件服务器

1.邮件传输所需组件及相关协议

MDA：邮件传送代理人

MTA:邮件发送代理人，postfix,sendmail,qmail，使用smtp协议(tcp 25)

MUA:邮件用户代理人，foxmail,thunderbird,使用pop3(110),imap(143)协议来接收邮件。

2.mta服务器用postfix来实现

3.zimbra卸载

[root@mail zcs-8.0.6_GA_5922.RHEL6_64.20131203103705]# ./install.sh -u

//默认安装目录

[root@mail zimbra]# /opt/zimbra

二.zimbra

1.网络规划

dns server：10.10.54.54

mail server:10.10.54.50(/opt >= 5GB)

2.配置DNS

[root@xiao54 ~]# vim /etc/named.conf 

========================================

options {

        listen-on port 53 { any; };

        listen-on-v6 port 53 { ::1; };

        directory       "/var/named";

        dump-file       "/var/named/data/cache_dump.db";

        statistics-file "/var/named/data/named_stats.txt";

        memstatistics-file "/var/named/data/named_mem_stats.txt";

        allow-query     { any; };

        recursion yes;

};

logging {

        channel default_debug {

                file "data/named.run";

               severity dynamic;

       };

};

zone "." IN {

        type hint;

        file "named.ca";

};

zone "xiaoq.com" IN {

       type master;

       file "mail.xiaoq.com";

};

5.邮件管理

后台管理：https://mail.xiaoq.com:7071 或者https：//10.10.54.50：7071

6.查看系统参数

可以通过zmlocalconfig -s命令查看系统的参数

$ postconf                                             //查看postfix的所有配置

$ zmlocalconfig                                        //查看各种组件的配置信息

$ zmlocalconfig -s|grep zimbra_ldap_userdn　　　　　　 //查看zimbra帐号在LDAP中的DN

$ zmlocalconfig -s|zimbra_ldap_password               //查看zimbra帐号在LDAP中的密码

$ zmlocalconfig -s|grep zimbra_mysql                   //查看mysql的配置信息

7.登录zimbra中mysql数据库（和之前装的mysql没有练习）

[root@xiao50 ~]# /opt/zimbra/bin/zmlocalconfig -uzimbra -pScwZtWEOhmMxK7ns067V0jfFHt42 -P7306 --socket=/opt/zimbra/db/mysql.sock 

##查看密码

[root@mail ~]# /opt/zimbra/bin/zmlocalconfig -s |grep zimbra_mysql

zimbra_mysql_password = ScwZtWEOhmMxK7ns067V0jfFHt42

##登录通用

 /opt/zimbra/mysql/bin/mysql -u`/opt/zimbra/bin/zmlocalconfig -s |grep "zimbra_mysql_user" | awk '{print $3}'` -p`/opt/zimbra/bin/zmlocalconfig -s |grep "zimbra_mysql_password" | awk '{print $3}'` -P7306 --sock=/opt/zimbra/db/mysql.sock
