linux – postfix多个IP SMTP横幅

前端之家收集整理的这篇文章主要介绍了linux – postfix多个IP SMTP横幅前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我已经安装了postfix 2.11.3,我们的服务器上有多个IP地址,我们想要托管两个域,隔离并运行在自己的IP上.
domain1  unix -       -       n       -       -       smtp
   -o smtp_bind_address=1.1.1.1
   -o smtp_helo_name=mail.abc.com
   -o syslog_name=postfix-mail.abc.com

domain2  unix -       -       n       -       -       smtp
   -o smtp_bind_address=2.2.2.2
   -o smtp_helo_name=mail.xyz.com
   -o syslog_name=postfix-mail.xyz.com

以下传输器/ etc / postfix / sender_transport也在main.cf中定义:

@abc.com    domain1:
@xyz.com    domain2:

重新启动postfix后,它停止侦听端口25:

[root@postfix-2.11.3]# telnet 1.1.1.1 25
Trying 1.1.1.1...
telnet: connect to address 1.1.1.1: Connection refused

但是,如果我在master.cf中使用以下行,它会在25上监听,如果我telnet,我可以看到横幅:

1.1.1.1:smtp inet  n - n - - smtpd -o myhostname=mail.abc.com 
2.2.2.2:smtp inet  n - n - - smtpd -o myhostname=mail.xyz.com

但我想告诉我的邮件服务器,当你发送电子邮件时使用特定域名就像sender_transport一样

我做错了什么?

笔记:

我从master.cf中删除了以下行,并替换为上面的domain1和domain2:

smtp      inet  n       -       n       -       -       smtpd

解决方法

解决方案 – 需要Postfix 2.7或更高版本:

/etc/postfix/master.cf

#smtp      inet  n       -       n       -       -       smtpd
127.0.0.1:smtp inet  n     -       n       -       -       smtpd
      -o syslog_name=postfix-localhost
      -o smtp_helo_name=localhost
      -o smtp_bind_address=127.0.0.1
      -o myhostname=localhost

65.xxx.xxx.100:smtp inet  n     -       n       -       -       smtpd
      -o syslog_name=postfix-mail.abc.com
      -o smtp_helo_name=mail.abc.com
      -o smtp_bind_address=65.xxx.xxx.100
      -o myhostname=mail.abc.com

65.xxx.xxx.200:smtp inet  n     -       n       -       -       smtpd
      -o syslog_name=postfix-mail.xyz.com
      -o smtp_helo_name=mail.zyx.com
      -o smtp_bind_address=65.xxx.xxx.200
      -o myhostname=mail.xyz.com

abc-out  unix -       -       n       -       -       smtp
   -o smtp_bind_address=65.xxx.xxx.100
   -o smtp_helo_name=mail.abc.com
   -o syslog_name=postfix-mail.abc.com

xyz-out  unix -       -       n       -       -       smtp
   -o smtp_bind_address=65.xxx.xxx.200
   -o smtp_helo_name=mail.xyz.com
   -o syslog_name=postfix-mail.xyz.com

/etc/postfix/main.cf中

sender_dependent_default_transport_maps = hash:/etc/postfix/sender_transport

/等/后缀/ sender_transport

# Use source IP - 65.xxx.xxx.100
@abc.com                abc-out:
@example.com            abc-out:

# Use source IP - 65.xxx.xxx.200 
@xyz.com                xyz-out:

运行命令以生成哈希数据库

postmap hash:/etc/postfix/sender_transport

重新启动/重新加载后缀

service postfix reload

测试

[root@localhost ~]# telnet 65.xxx.xxx.200 25
Trying 65.xxx.xxx.200...
Connected to 65.xxx.xxx.200.
Escape character is '^]'.
