linux配置mail server
一、配置yum安裝工具
① 進入yum目錄
[root@bj ~]# cd /etc/yum.repos.d
② 配置yum.repo
[root@bj yum.repos.d]# cprhel-debuginfo.repo yum.repo
將yum.repo修改成以下內容
[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 把光盤掛載到/media目錄上
[root@bj ~]# mount /dev/cdrom /media/
二、通過yum安裝sendmail、dovecot
[root@bj ~]# yum install -y sendmail*
----sendmail 負責發送郵件（smtp 協議 ，port 25）
[root@bj ~]# yum install -y dovecot*
----dovecot 負責接收郵件（pop3 協議，port 110，imap 協議 ，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，將其改為0.0.0.0（默認sendmail只負責發送本地郵件，0.0.0.0將監聽任何地址的郵件）
③ 啟動sendmail服務
1、修改/etc/hosts
192.168.6.130 bj.siqian.com (主機名設為主機名.域名的方式，否則收不到郵件）
2、修改/etc/sysconfig/network
hostname=bj.siqian.com
3、然後再執行
hostname bj.siqian.com
4、啟動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 配置郵件接收
[root@bj ~]# vi /etc/dovecot.conf
把其中的：
#protocols = imap pop3 lmtp
----取消注釋，改為
protocols = imap pop3 lmtp
⑤ 啟動dovecot服務
service dovecotstart
-----查看 pop3，imap
[root@bj ~]# netstat -an | grep :110
tcp 0 0 :::110 :::* LISTEN
四、收發郵件
①寫郵件，發送郵件
[root@bj ~]# mail -s "oracle"oracle
test mail for oracle!!!
Cc: root
抄送功能為快捷鍵ctl+d
②接收郵件
[root@bj ~]# mail
