1.检查是否安装了sendmail

[root@sendmail ~]# rpm -qa | grep sendmail                                                                 

sendmail-8.13.8-8.el5                                                             

通过上面查询,看到默认安装包不全,配置yum安装所需包

2.配置yum,略。

3.yum安装

[root@sendmail ~]# yum install sendmail*                                                           

Installing:

 sendmail-cf        x86_64     8.13.8-8.el5     rhel-debuginfo     306 k

 sendmail-devel     i386       8.13.8-8.el5     rhel-debuginfo     128 k

 sendmail-devel     x86_64     8.13.8-8.el5     rhel-debuginfo     133 k

 sendmail-doc       x86_64     8.13.8-8.el5     rhel-debuginfo     665 k

4.再次检查安装结果

[root@sendmail ~]# rpm -qa | grep sendmail

sendmail-cf-8.13.8-8.el5

sendmail-doc-8.13.8-8.el5

sendmail-8.13.8-8.el5

sendmail-devel-8.13.8-8.el5

sendmail-devel-8.13.8-8.el5

5.开始配置sendmail文件-/etc/mail/sendmail.cf

[root@sendmail ~]# vi /etc/mail/sendmail.mc

修改116

DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA')dnl

修改155

155 LOCAL_DOMAIN(`localhost.localdomain')dnl

155 LOCAL_DOMAIN(`sendmail')dnl  //此处的sendmail值为域名,建议设置为带.com标识

6.m4生成配置文件sendmail.cf

[root@sendmail ~]# m4 /etc/mail/sendmail.mc /etc/mail/sendmail.cf

7.修改local-host-names,设置可以接收邮件的主机

[root@sendmail mail]# vi local-host-names

修改后如下

# local-host-names - include all aliases for your machine here.

sendmail

保存,退出

8.修改ACCESS文件,设置允许使用的客户端

[root@sendmail /]# vi /etc/mail/access

修改之后如下

# by default we allow relaying from localhost...

Connect:localhost.localdomain           RELAY

Connect:localhost                       RELAY

Connect:127.0.0.1                       RELAY

Connect:qq.com                          RELAY

10.133.90                               RELAY

9.重新生成access.db

[root@sendmail ~]# cd /etc/mail

[root@sendmail mail]# make access.db

10.安装imap,配置popdovecot套件)

[root@sendmail /]# yum -y install dovecot

11.查看hosts文件是否有解析

[root@sendmail /]# vi /etc/hosts

修改之后

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1               sendmail localhost.localdomain localhost

::1             localhost6.localdomain6 localhost6

192.168.0.131   sendmail                //此处如果域名和主机名不同,域名也需要写

12.重新启动各项服务

 [root@sendmail /]# service sendmail restart

Shutting down sm-client: [  OK  ]

Shutting down sendmail: [  OK  ]

Starting sendmail: [  OK  ]

Starting sm-client: [  OK  ]

[root@sendmail /]# service dovecot restart

Stopping Dovecot Imap: [FAILED]

Starting Dovecot Imap: [  OK  ]

[root@sendmail /]# service saslauthd restart

Stopping saslauthd: [FAILED]

Starting saslauthd: [  OK  ]

将上面各项服务设置为开机启动

[root@sendmail /]# chkconfig sendmail on

[root@sendmail /]# chkconfig dovecot on

[root@sendmail /]# chkconfig saslauthd on

配置之后结果如下

[root@sendmail /]# chkconfig --list | grep sendmail

sendmail        0:off   1:off   2:on    3:on    4:on    5:on    6:off

[root@sendmail /]# chkconfig --list | grep dovecot

dovecot         0:off   1:off   2:on    3:on    4:on    5:on    6:off

[root@sendmail /]# chkconfig --list | grep saslauthd

saslauthd       0:off   1:off   2:on    3:on    4:on    5:on    6:off

13.测试端口

 

telnet25端口测试截图

clip_image002[4]

clip_image004[4]

telnet 110端口截图

clip_image006[4]

clip_image008[4]

14.建立邮件测试账户,使用foxmail作为客户端进行收发邮件测试

[root@sendmail mail]# useradd sendmailtest

[root@sendmail mail]# passwd sendmailtest

Changing password for user sendmailtest.

New UNIX password:

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

使用终端root账户发送消息给sendmailtest用户

[root@sendmail mail]# mail sendmailtest@sendmail

Subject: 这是一封测试邮件,由root发送

收到内容请回复    

Cc:

[root@sendmail mail]#

[root@sendmail mail]#

之后登录foxmail,查看是否已经收到

clip_image010[4]

可以看到刚刚由root发送出来的邮件,现回复一封邮件给root

clip_image012[4]

点击发送之后,回到终端,按下回车,会看到有一条消息提示

You have new mail in /var/spool/mail/root

[root@sendmail mail]#

You have new mail in /var/spool/mail/root

[root@sendmail mail]#
