include "/etc/rndc.key"文件末尾加上自己的域名abc.com。
[root@rhel5 Server]# cd /var/named #进入解析文件的目录
[root@rhel5 named]# cp named.local abc.com.zone #生成自己的解析文件
这个时候因为是root权限,但是DNS解析又需要named这个用户,所以把abc.com.zone的拥有着更改为named,如下:
[root@rhel5 named]# chown named.named abc.com.zone
[root@rhel5 named]# vim abc.com.zone
$TTL 86400
@ IN SOA abc.com. root.localhost. (

3600000 ; Expire
86400 ) ; Minimum
IN NS 192.168.1.95
IN MX 5 mail
mail IN A 192.168.1.95
pop3 IN A 192.168.1.95
smtp IN A 192.168.1.95
服务器的地址为192.168.1.95,DNS地址为本机的IP。
[root@rhel5 named]# nslookup mail.abc.com
Server: 192.168.1.95
Address: 192.168.1.95#53
Name: mail.abc.com
Address: 192.168.1.95

安装sendmail
Sendmail也需要3个包支持
sendmail-8.13.8-2.el5.i386.rpm,sendmail-cf-8.13.8-2.el5.i386.rpm,sendmail-doc-8.13.8-
2.el5.i386.rpm,
把服务器监听地址改为服务器的IP地址:
[root@rhel5 Server]# vim /etc/mail/sendmail.cf
# SMTP daemon options
O DaemonPortOptions=Port=smtp,Addr=192.168.1.95, Name=MTA
# SMTP client options
O ClientPortOptions=Family=inet, Address=192.168.1.95
把sendmail服务器的域名添加进去:
[root@rhel5 Server]# vim /etc/mail/local-host-names
# local-host-names - include all aliases for your machine here.

安装dovecot,在rhel5里dovecot整合了imap。
[root@rhel5 Server]# rpm -ivh dovecot-1.0-1.2.rc15.el5.i386.rpm
[root@rhel5 Server]# service named start
[root@rhel5 Server]# service dovecot start
[root@rhel5 Server]# service sendmail start
[root@rhel5 Server]# chkconfig dovecot on

验证所有的服务全起来了
[root@rhel5 Server]# netstat -ntla

添加测试用户:
[root@rhel5 Server]# useradd test1
[root@rhel5 Server]# passwd test1
Changing password for user test1.
New UNIX password:
BAD PASSWORD: it is WAY too short
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@rhel5 Server]# useradd test2
[root@rhel5 Server]# passwd test2
Changing password for user test2.
New UNIX password:
BAD PASSWORD: it is WAY too short
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
