3、vim /var/named/1.168.192.in-addr.arpa.zone
4、nslookup查看
三、sendmail简单配置
1、安装sendmail
root@dns ~]# mount /dev/hdc /mnt/dvd/
mount: block device /dev/hdc is write-protected, mounting read-only
[root@dns ~]# cd /mnt/dvd/Server/
[root@dns Server]# rpm -qa | grep sendmail
sendmail-8.13.8-2.el5
[root@dns Server]# ls sendmail*
sendmail-8.13.8-2.el5.i386.rpm sendmail-devel-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
[root@dns Server]# rpm -ivh --aid sendmail-cf-8.13.8-2.el5.i386.rpm
warning: sendmail-cf-8.13.8-2.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

1:sendmail-doc ########################################### [100%]
[root@dns Server]#
[root@dns Server]# rpm -qa | grep sendmail
sendmail-devel-8.13.8-2.el5
sendmail-doc-8.13.8-2.el5
sendmail-cf-8.13.8-2.el5
sendmail-8.13.8-2.el5
[root@dns Server]# rpm -qa | grep m4
m4-1.4.5-3.el5.1
2、修改vim /etc/mail/sendmail.mc
第116行将smtp侦听范围从127.0.0.1改为0.0.0.0
第155行修改成自己域：LOCAL_DOMAIN(`benet.com')dnl
3、使用m4命令生成sendmail.cf文件
m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
4、修改local-host-names文件添加域名及主机名
vim /etc/mail/local-host-names
[root@dns Server]# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
[root@dns Server]# vim /etc/mail/local-host-names
# local-host-names - include all aliases for your machine here.
benet.com.
mail.benet.com.
~
~
~
"/etc/mail/local-host-names" 3L, 91C 已写入
[root@dns Server]#
5、安装Dovecot软件包（POP3和IMAP）
[root@dns Server]# rpm -ivh --aid mysql-5.0.45-7.el5.i386.rpm
warning: mysql-5.0.45-7.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
error: Failed dependencies:

1:dovecot ########################################### [100%]
6、启动sendmail和dovecot服务
[root@dns Server]# service sendmail restart
关闭 sm-client： [确定]
关闭 sendmail： [确定]
启动 sendmail： [确定]
启动 sm-client： [确定]
[root@dns Server]# service dovecot restart
停止 Dovecot Imap： [确定]
启动 Dovecot Imap： [确定]
[root@dns Server]#
7、查看端口netstat
[root@dns Server]# netstat -ntl

8、验证Sendmail的SMTP认证功能telnet localhost 25
[root@dns Server]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.

2、启动服务和netstat查看端口
3、初始化OpenWebmail系统
[root@dns dvd]# cd /var/www/cgi-bin/openwebmail/
You have new mail in /var/spool/mail/root
[root@dns openwebmail]# ls

Welcome to the OpenWebMail!
This program is going to send a short message back to the developer,
so we could have the idea that who is installing and how many sites are
using this software, the content to be sent is:
OS: Linux 2.6.18-128.el5 i686
Perl: 5.008008
WebMail: OpenWebMail 2.53 20080123
Send the site report?(Y/n) y
sending report...
Thank you.
[root@dns ~]#
4、修改配置文件中的设置项
[root@dns etc]# vim /var/www/cgi-bin/openwebmail/etc/openwebmail.conf
修改14行domainnames auto改成domainnames benet.com
修改64行default_language en改成default_language zh_CN.GB2312
修改87行default_iconset Cool3D.English改成default_iconset Cool3D.chinese.Simplified
5、IE浏览器查看http://mail.benet.com/cgi-bin/openwebmail/openwebmail.pl（会出错是SELinux导致）
6、修改系统的SELinux设置
[root@dns etc]# cd
[root@dns ~]# touch /var/log/openwebmail.log
[root@dns ~]# chcon -u system_u /var/log/openwebmail.log
[root@dns ~]# chcon -t httpd_sys_script_rw_t /var/log/openwebmail.log
[root@dns ~]# chcon -t httpd_unconfined_script_exec_t /var/www/cgi-bin/openwebmail/openwebmail*
[root@dns ~]#
7、IE设置和OE接收和发送
配置完成后输入http://mail.benet.com/webmail访问
选择设置个人模板
给李四lisi@benet.com发送邮件
OE接收查看并回复
