.. 并获得了几个 BL 的 IP..
此 Postfix 服务器设置为与 Exchange 服务器之间中继邮件。
我看到很多 postmaster 或 root @mail.mydomain.com 从 postfix 发出，而不是正确的邮件地址 @mydomain.com
该服务器正在运行 SpamAssassin、Amavis、PostScreen 和 OpenDMARC。我已三次检查，除了外部 DNS（Cloudfare）和内部 DNS（Active Directory）之外，没有配置文件声明 mail.mydomain.com，原因很明显。
主机名文件是：
mydomain.com
hosts 文件是：
127.0.0.1 localhost
127.0.1.1 mydomain.com
邮件名称是：
mydomain.com
外部和内部 DNS 是：
10.2.0.6 A mail.mydomain.com
my.pbl.ip.add A mail.mydomain.com
mydomain.com MX mail.mydomain.com
我是这样定义的：
notify_classes = bounce, delay, policy, protocol, resource, software
2bounce_notice_recipient = [email protected]
bounce_notice_recipient = [email protected]
delay_notice_recipient = [email protected]
error_notice_recipient = [email protected]
我需要知道要进行哪些调整才能使其停止使用@mail.mydomain.com 发送这些邮政局长和根电子邮件，并在我进入另一个列表之前开始使用正确的@mydomain.com。
请帮忙！
先感谢您！

使用“newaliases”命令未更新别名。此后，它停止尝试使用@mail.mydomain.com
