I have a server hosting with one domain and several subdomain a records with dedicated by different IPs.

In order to avoid any possibility of blacklisting of one IP, I would like to make sure that each subdomain uses its own IP to send mail and that the server primary IP or host name info does not appear in the message received header.

I am not sure of what are the EXIM configurations which need to be made to achieve that. Can somebody provide me the full description of what needs to be done or direct me to a link providing that?

  1. 编辑 /etc/exim.conf。 remote_smtp driver = smtp interface = x.x.x.x # Change with your new IP.
  2. 保存更改并退出 conf 文件。
  3. chattr +ia /etc/exim.conf [否则 exim 将覆盖我们所做的更改]
  4. 重启exim。

是的。您必须在 /etc/mailips 文件中更新您的新邮件 IP，并在 WHM 的 Exim 配置管理器中启用以下 2 个选项来更改 cpanel 服务器的邮件服务器 IP

Reference /etc/mailhelo for outgoing SMTP HELO
Reference /etc/mailips for outgoing SMTP connections
