在服务器上配置一个SMTP邮件服务可能是在日常工作中经常会遇到的需要，比如在做一些简单测试的时候。

配置步骤无比简单，废话不说：

1，yum -y install mail

2，编辑/etc/mail.rc，配置一些smtp相关内容

3，没有了...

安装mail

详细输出过程，记录如下

[root@thatsit ~]# yum -y install mail已加载插件:fastestmirror设置安装进程Loading mirror speeds from cached hostfileCould not get metalink https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=x86_64 error was14: Peer cert cannot be verified or peer cert invalid* base: mirrors.yun-idc.com* epel: mirror.lzu.edu.cn* extras: mirrors.yun-idc.com* updates: mirrors.yun-idc.combase | 3.7 kB 00:00extras | 3.4 kB 00:00updates | 3.4 kB 00:00解决依赖关系--> 执行事务检查---> Package mailx.x86_64 0:12.4-8.el6_6 will be 安装--> 完成依赖关系计算依赖关系解决===============================================================================================================================================================================================软件包 架构 版本 仓库 大小===============================================================================================================================================================================================正在安装:mailx x86_64 12.4-8.el6_6 base 235 k事务概要===============================================================================================================================================================================================Install 1 Package(s)总下载量:235 kInstalled size: 452 k下载软件包:mailx-12.4-8.el6_6.x86_64.rpm | 235 kB 00:00运行 rpm_check_debug执行事务测试事务测试成功执行事务正在安装 : mailx-12.4-8.el6_6.x86_64 1/1warning: /etc/mail.rc created as /etc/mail.rc.rpmnewVerifying : mailx-12.4-8.el6_6.x86_64 1/1已安装:mailx.x86_64 0:12.4-8.el6_6完毕！[root@thatsit ~]#

配置SMTP

[root@shipeng01 ~]# vim /etc/mail.rc[root@thatsit ~]# cat /etc/mail.rcset from=my_test_mail_address@163.comset smtp=smtp.163.comset smtp-auth-user=my_test_mail_addressset smtp-auth-password=passwd_of_my_test_mail_address123set smtp-auth=login[root@thatsit ~]#

测试

mailx和mail的关系

这里大家可能也看到了，上面测试命令里用了mailx，跟有些文档里用的mail命令不一样，那么这两者之间的关系是什么呢？我们来看一下：

[root@thatsit ~]# which mail/bin/mail[root@thatsit ~]# ll /bin/maillrwxrwxrwx 1 root root 22 11月 15 10:47 /bin/mail -> /etc/alternatives/mail[root@thatsit ~]# ll /etc/alternatives/maillrwxrwxrwx 1 root root 10 11月 15 10:47 /etc/alternatives/mail -> /bin/mailx[root@thatsit ~]#

大家也看到了，其实mail就是mailx软链的软链。因此在使用上，这两个命令一样的：

[root@thatsit ~]# echo "hehe" | mail -v -s "test" my_qq_number@qq.comResolving host smtp.163.com . . . done.Connecting to 220.181.12.11 . . . connected.220 163.com Anti-spam GT for Coremail System (163com[20141201])>>> EHLO thatsit250-mail250-PIPELINING250-AUTH LOGIN PLAIN250-AUTH=LOGIN PLAIN250-coremail 1Uxr2xKj7kG0xkI17xGrU7I0s8FY2U3Uj8Cz28x1UUUUU7Ic2I0Y2UFbVUZKUCa0xDrUUUUj250-STARTTLS250 8BITMIME>>> AUTH LOGIN334 dXNlcm5hbWU6>>> dGhhdHNtYWls334 UGFzc3dvcmQ6>>> IUAjdGhhdHNtYWlsMTIz235 Authentication successful>>> MAIL FROM:
