8.安装邮件接收服务器：（MAA）
[root@mail cdrom]# cd /mnt/cdrom/Server
[root@mail Server]# ll dove*
-r--r--r-- 264 root root 1736855 Dec 10 2008 dovecot-1.0.7-7.el5.i386.rpm
[root@mail Server]# rpm -ivh dovecot-1.0.7-7.el5.i386.rpm
warning: dovecot-1.0.7-7.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

[root@mail Server]# rpm -ql dovecot |less
/etc/dovecot.conf //主配置文件
/etc/pam.d/dovecot //PAM
/etc/pki/dovecot //支持证书！
/etc/pki/dovecot/certs
[root@mail Server]# vim /etc/dovecot.conf
该行可有选择地使用！
10.启动sendmail服务，查看其端口
[root@mail Server]# netstat -tupln |grep send
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 3824/sendmail: acce
注意：127.0.0.0.1只能在本地进行进行中继~
11.创建本地账号：
[root@mail mail]# useradd user1
[root@mail mail]# passwd user1
Changing password for user user1.
New UNIX password:
BAD PASSWORD: it is WAY too short
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@mail mail]# useradd user2
[root@mail mail]# passwd user2
12.本地写封信测试：
普通测试：
[root@mail mail]# mail -s gjp user1
welcome!
.
Cc:
[root@mail mail]# su - user1
[user1@mail ~]$ mail
Mail version 8.1 6/6/93. Type ? for help.

telnet 所监听的端口测试：
[root@mail Server]# telnet 127.0.0.1 25
