一、 安裝 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

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 將smtp偵聽範圍從127.0.0.1改成0.0.0.0

第 155行修改爲本身域： 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 文件添加域名及主機名

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 已寫入

[root@dns Server]#

5 、安裝Dovecot 軟件包（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

六、啓動sendmail和dovecot服務

[root@dns Server]# service sendmail restart

關閉 sm-client： [肯定]

關閉 sendmail： [肯定]

啓動 sendmail： [肯定]

啓動 sm-client： [肯定]

[root@dns Server]# service dovecot restart

中止 Dovecot Imap： [肯定]

啓動 Dovecot Imap： [肯定]

[root@dns Server]#

7 、查看端口netstat

[root@dns Server]# netstat -ntl

Active Internet connections (only servers)

unix 2 [ ] STREAM CONNECTED 10143 /var/run/setrans/.setrans-unix

8 、驗證Sendmail 的SMTP 認證功能telnet localhost 25

[root@dns Server]# telnet localhost 25
