Linux平台服务器搭建：[4]sendmail服务器

1、一、软件安装主要包

dovecot-1.0.7-7.el5.i386.rpm //imap (收邮件)

sendmail-8.13.8-2el5.i386.rpm      

 sendmail-cf-8.13.8-2el5.i386.rpm //配置文件

cyrus-sasl-2.1.22-5.el5_4.3.i386.rpm//smtp验证可直接用图形化界面安装,钩选"邮件服务器"进行安装

查看是否安装以上的包

#rpm –qa|grep  sendmail  

显示如下

sendmail-8.13.8-2el5.i386.rpm       

sendmail-cf-8.13.8-2el5.i386.rpm

2、二、配置sendmail配置主目录:

/etc/maildovecot配置:

/etc/dovecot.conf  //保持默认

A:-------------------------------

#cd /etc/mail#vi sendmail.mc(1)修改116行的127.0.0.1为0.0.0.0   //所有人都可以使用本邮件服务器(2)第52行和53行，把最前面的dnl删除  (注意里面每个语句都要顶格写，否则后面重启服务会报Starting sendmail: 5545.0.0 /etc/mail/sendmail.cf: line 39: unknown configuration line)  //smtp验证后允许所有域转发  不管access.db怎么设置TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnldefine(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGINPLAIN')dnl

#m4 sendmail.mc > sendmail.cf   //生成配置、

接下来:-------------------------------

#vi local-host-namesim-sh.com  //加入邮件域名

接下来:-------------------------------

#vi access      //加入邮件域名im-sh.com  RELAY //允许发邮件到im-sh.com  smtp不验证也可以发至qq.com211.67.134  RELAY //允许这个网段

#makemap hash /etc/mail/access.db < /etc/mail/access

# db_dump -p /etc/mail/access.db

3、三 :-------------------------------

编辑dovecot配置文件 

[root@mail /]# vi /etc/dovecot.conf查找， 第20行把注释去掉改成：

protocols = imap imaps pop3 pop3s#service dovecot start    //启动imap

#service saslauthd start   //启动saslauthd

4、四 :-------------------------------

修改IPTABLES防火墙设置允许SMTP  及添加其它端口:110设置开机自启动

chkconfig --level 35 

sendmail onchkconfig --level 35 

dovecot on chkconfig --level 35 

saslauthd onchkconfig --level 35 httpd on

5、五：测试sendmail程序发邮件，可以用mail命令实现，1，首先在/目录下建个文件1.txt内容如下 

你好，     本信件来自LINUX sendmail 邮件服务器，仅为测试使用！假如您收到本邮件说明Crownxiaobo的邮件系统已经测试成功！！！！  您的friend's crownxiaobo

2，在终端窗口中输入命令

[root@localhost mail]# mail -s "Linux mailtest by wangxiaobo" 676252567@qq.com < /1.txt -- -f wangxiaobo@root.com -F cc 

[root@localhost mail]# mail -s "Linux mailtest by wangxiaobo" 1020339572@qq.com < /1.txt -- -f wangxiaobo@root.com -F cc 

6、六： 打开扣扣邮箱就可以看到收到的邮件如下图
