阿里云ECS 操作系统CentOS下安装IRedMail收发邮件

使用阿里云ECS制作IRedMail收发邮件服务器详细过程如下

1、什么是IRedMail？

iRedMail - 免费、开源邮件服务解决方案
以最佳的方式搭建基于 Linux/BSD 和开源软件的邮件服务器。始于 2007 年。
支持 Red Hat Enterprise Linux、CentOS、Debian、Ubuntu、FreeBSD、OpenBSD
只需几分钟，iRedMail 即可为您部署一台完全基于开源软件、功能完善的邮件服务器，而且，免费。
使用的都是开源领域有口皆碑的开源软件，并预设了最佳配置，让您可以“开箱即用”。

2、安装IRedMail

安装文档在这，设置好之后要设置阿里云域名A和MX的解析记录，如下：

值得注意的一点是：阿里云ECS是禁用SMTP发件的25端口的，如果你想使用就要申请了，虽然你能够在ECS的安全规则下打开这个端口，但是阿里云技术文档也说了，实际还是被封的！

所以我这里只当收件功能，发件我没试！

3、配置文件

安装好IRedMail之后，接着你要设置/etc/postfix/main.cf下的主机和域名，如下：

inet_protocols = ipv4
virtual_alias_domains =
myhostname = mail.xfindzp.com
myorigin = mail.xfindzp.com
allow_percent_hack = no
swap_bangpath = no
mydomain = xfindzp.com
mydestination = $myhostname, localhost, localhost.localdomain, localhost.$myhostname
biff = no
inet_interfaces = all
mynetworks = 0.0.0.0/0

然后再设置ECS的主机名，如下 ：

然后重启下ECS即可生效

接着设置打开后台管理系统，添加域：mail.xfindzp.com和用户：[e-mail]，如下：

查看下mail.xfindzp.com在阿里云ECS服务器上解析情况：

☁  ~  telnet mail.xfindzp.com 110
Trying 47.97.104.97...
Connected to mail.xfindzp.com.
Escape character is '^]'.
+OK Dovecot ready.
user [e-mail]
+OK
pass 23456789
+OK Logged in.
list
+OK 3 messages:
1 2781
2 2745
3 2853

4、测试收信

用我自己的qq邮箱发送的时候报下面的错：

如何解决这个问题呢，这个我查看了/var/log/maillog日志和/var/log/dovecot.log日志，发现报错：

Jul  8 15:46:14 mail postfix/smtpd[2272]: NOQUEUE: reject: RCPT from unknown[14.17.44.32]: 450 4.1.8 <[e-mail]>: Sender address rejected: Domain not found; from=<[e-mail]> to=<[e-mail]> proto=ESMTP helo=<smtpbg337.qq.com>

这个问题值到我提交到阿里云工单上面技术人员才帮我解决问题，如下：

问题原因找到了，原来是var/spool/postfix/etc/resolv.conf文件和/etc/resolv.conf有差异
把后面文件里面的ip替换前面文件里面的ip才搞定，真是个坑，还好解决了，再测试发信试试

# vim /var/spool/postfix/etc/resolv.conf

options timeout:1 attempts:1 rotate
nameserver 10.202.72.116
nameserver 10.202.72.118
替换成：
options timeout:1 attempts:1 rotate
nameserver 100.100.2.138
nameserver 100.100.2.136

# vim /etc/resolv.conf

nameserver 100.100.2.138
nameserver 100.100.2.136
options timeout:2 attempts:3 rotate single-request-reopen

成功

再看看后台，也是收到了！

至此收信功能圆满完成！

总结：

1、一开始我并没有安装IRedMail，而是在ECS上面安装postfix+dovecot+extmail，但是添加域以及收发件都是不成功的，没办法到网上找到了ECS的境像：iRedMail 运行环境镜像使用指南

镜像环境是：CentOS 6.5 64位

这个他已经帮你搭建好了，你只要按照他的说明文档来就好，而且账户和密码什么的已经保存到/alidata/account.log里面了，直接拿来登录就好！

问题：

1、安装过程中遇到好多问题，都无法解决，找了好多人，加了好多群，但是值到我使用IRedMail才看到希望
