linux配置mail server
linux配置mail server
linux配置mail server一、配置yum安装工具
① 进入yum目录
[root@bj ~]# cd /etc/yum.repos.d
② 配置yum.repo
[root@bj yum.repos.d]# cprhel-debuginfo.repo yum.repo
将yum.repo修改成以下内容
[root@bj yum.repos.d]# cat yum.repo
[Base]
name=Red Hat Enterprise Linux
baseurl=file:///media/Server
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
③ 把光盘挂载到/media目录上
[root@bj ~]# mount /dev/cdrom /media/
二、通过yum安装sendmail、dovecot
[root@bj ~]# yum install -y sendmail*
----sendmail 负责发送邮件（smtp 协议 ，port 25）
[root@bj ~]# yum install -y dovecot*
----dovecot 负责接收邮件（pop3 协议，port 110，imap 协议 ，port 143）
三、配置sendmail
① cd /etc/mail
m4 sendmail.cf > sendmail.mc
② vi sendmail.mc
----查找127.0.0.1，将其改为0.0.0.0（默认sendmail只负责发送本地邮件，0.0.0.0将监听任何地址的邮件）
③ 启动sendmail服务
1、修改/etc/hosts
192.168.6.130 bj.siqian.com (主机名设为主机名.域名的方式，否则收不到邮件）
2、修改/etc/sysconfig/network
hostname=bj.siqian.com
3、然后再执行
hostname bj.siqian.com
4、启动sendmail
service sendmail start
5、查看smtp
[root@bj ~]# netstat -an | grep :25
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN
④ 配置邮件接收
[root@bj ~]# vi /etc/dovecot.conf
把其中的：
#protocols = imap pop3 lmtp
----取消注释，改为
protocols = imap pop3 lmtp
⑤ 启动dovecot服务
service dovecotstart
-----查看 pop3，imap
[root@bj ~]# netstat -an | grep :110
tcp 0 0 :::110 :::* LISTEN
四、收发邮件
①写邮件，发送邮件
[root@bj ~]# mail -s "oracle"oracle
test mail for oracle!!!
Cc: root
抄送功能为快捷键ctl+d
②接收邮件
[root@bj ~]# mail
