我有 4 个不同的用户需要他们自己的 IP 地址才能将邮件发送到特定地址。如何配置这些用户通过他们自己的 IP 地址发送？我可以在我的虚拟主机配置中将其作为传输吗？一个问题是，无论选择什么，它都必须是可扩展的，以添加第五个而无需启动/停止后缀，可能是重新加载。但是从我们的 vhost 数据库中提取路由是理想的解决方案。

您将需要为您将在您的系统中使用的每个 IP 进行传输master.cf

user1  unix -       -       n       -       -       smtp
      -o syslog_name=postfix-user1
      -o smtp_bind_address=1.2.3.4
      #-o smtp_bind_address6=XXX:ZZZ:EEE:999::2

user2  unix -       -       n       -       -       smtp
      -o syslog_name=postfix-user2
      -o smtp_bind_address=1.2.3.5
      #-o smtp_bind_address6=XXX:ZZZ:EEE:999::2

在你的 main.cf

sender_dependent_default_transport_maps = hash:/etc/postfix/transport.cf

#/etc/postfix/transport.cf
user1@domain.tld user1:
user2@domain.tld user2:

有了这个想法，您可以将查找类型更改mysql/pgsql为查询数据库，但您需要在您的master.cf

另一种选择可能是使用单独的 Postfix 实例——每个实例都绑定到一个 IP 地址——为此。这也允许单独的横幅等。
