我只想限制运行 Postfix 的 Ubuntu 系统中的特定列表来发送电子邮件，当然我可以接收外部电子邮件（发件人/收件人）
假设我的域名是tt.net
这是我从我的主机 OVH 收到的信息::
Our Antispam protection has detected a large amount of spam being sent from one of your IPs:
149.202.xx.xx
In order to ensure the security of our network the outgoing traffic from your server to
ports 25 has been suspended.
In order for you to check, here is a sample of the blocked emails:

那些地址不是我的！并且未在我的虚拟列表中配置。
