我是 Postfix 的新手，直到现在我才开始使用 Exim，我无法在 Postfix 上进行配置，而我可以使用 Exim 进行配置
我有 3 个域名，每个域名有 5 个电子邮件地址
domain1.com 具有[电子邮件保护]，[电子邮件保护]...[电子邮件保护] domain2.com 与[电子邮件保护]，[电子邮件保护]...[电子邮件保护] domain3.com 与[电子邮件保护]，[电子邮件保护]...[电子邮件保护]
对于每个用户，我都希望指定一个唯一的 IP 来发送电子邮件。他将连接到 smtpXX.domainX.com，并且我希望该外发电子邮件来自 smtpXX.domainX.com 的 IP，并且邮件 HELO 也为 smtpXX.domainX.com，
我到现在为止尝试了不同的解决方案，最后一个 https://serverfault.com/a/650326/443941 但仍然没有成功：
smtp 登录正在端口 587 上运行
我也设置了：
31.xx.xx.xx:submission inet n - n - - smtpd
我尝试从路由器后面的家用电脑连接，我尝试连接到smtp11.domain1.com其中 ip 是 31.xx.xx.189，通过我的 postfix 设置的接收头是正常的，但是接收服务器可以看到我的服务器的主机名 (server.hostname.com) 以及服务器的主 ip...下面是我得到的结果：

有人能帮我吗？我使用 Centos 7、postfix 2.10、virtualmin（我也在 CWP 上尝试过，结果相同）

看一眼Postfix 架构概述。在您master.cf的smtpd为接收使用不同的设置（IP 和协议）发送邮件。但是，Postfix交付使用不同的组件发送邮件：smtp。
您需要配置其他 SMTP 客户端（传出运输） 在你的
master.conf：smtp1-out unix - - n - - smtp -o smtp_bind_address=31.xx.xx.85 -o smtp_helo_name=smtp1.example.com -o syslog_name=postfix-smtp1 smtp12-out unix - - n - - smtp -o smtp_bind_address=31.xx.xx.189 -o smtp_helo_name=smtp12.example.com -o syslog_name=postfix-smtp12然后您需要在以下位置配置发送方相关的传输图
main.cf：sender_dependent_default_transport_maps = hash:/etc/postfix/sender_transport您
/etc/postfix/sender_transport需要将您的域映射到传输：# Use source IP - 31.xx.xx.85 @example.com smtp1-out: # Use source IP - 31.xx.xx.189 @example.net smtp12-out:由于这是一种
hash:类型查找表，sudo postmap /etc/postfix/sender_transport。
