我有一个具有多个 IP 地址的 VPS：
- venet0:0 xxx2
- venet0:1 xxx3
- venet0:2 xxx4
- venet0:3 xxx5
所有 IP 都有 A 记录
- m2.domain.com -> xxx2
- m3.domain.com -> xxx3
- m4.domain.com -> xxx4
- m5.domain.com -> xxx5
和 rDNS 记录
- xxx2 -> m2.domain.com
- xxx3 -> m3.domain.com
- xxx4 -> m4.domain.com
- xxx5 -> m5.domain.com
我已经安装了 postfix + dovecot + mysql + opendkim。
这是我的一部分主配置文件启动 SMTP：
x.x.x.2:smtp inet n - - - - smtpd -o myhostname=m2.domain.com
x.x.x.3:smtp inet n - - - - smtpd -o myhostname=m3.domain.com
x.x.x.4:smtp inet n - - - - smtpd -o myhostname=m4.domain.com
x.x.x.5:smtp inet n - - - - smtpd -o myhostname=m5.domain.com
当我 telnet 到m2.域名.com:25我得到了预期HELO m2.domain.com对于所有子域名也是如此。
一切都很好，但在邮件标题中我写错了
直升机
X-Spam-Last-External-HELO: localhost.localdomain.
我没有设置$我的域名在主配置文件以及来自的价值观主配置文件没有覆盖它。
如何为所有 IP 动态设置 HELO？
