我有一个VPS多个IP地址：
所有IP都有Alogging
和rDNSlogging
我已经安装了postfix + dovecot + mysql + opendkim。
这是我的master.cf启动SMTP的一部分：
xxx2:smtp inet n - - - - smtpd -o myhostname=m2.domain.com xxx3:smtp inet n - - - - smtpd -o myhostname=m3.domain.com xxx4:smtp inet n - - - - smtpd -o myhostname=m4.domain.com xxx5:smtp inet n - - - - smtpd -o myhostname=m5.domain.com 当我telnet到m2.domain.com:25我得到预期的HELO m2.domain.com等所有子域。
一切正常，但在邮件标题中，我有错误的HELO X-Spam-Last-External-HELO: localhost.localdomain.
我没有在main.cf中设置$ mydomain ， master.cf中的值没有覆盖它。
如何为所有IPdynamic设置HELO？
这是一个完整的标题

我已经看到了相关的链接，但问题是，所有传出的电子邮件将来自一个域（domain.com），所以交通地图和多个实例不会做这项工作，或者我不知道如何。
