我有域名“example.com”，以及两个 Redhat VM“Clinet1.example.com”和“Client2.example.com”，我安装了 postfix 服务器“server.example.com”。我在客户端 1 和客户端 2 上都进行了配置，以使用服务器作为中继主机。当我从客户端 1 或客户端 2 向服务器发送电子邮件时，它会显示在邮件目录中，但是当我从客户端 1 发送到客户端 2 或反之亦然时，它会显示在邮件目录中。在服务器中也是如此，无法到达接收的客户端。服务器上的 /etc/postfix/main.cf 如下
myhostname = server.example.com
mydomain = example.com
myorigin = $myhostname
inet_interfaces = all
inet_protocols = ipv4
mydestination = client1.$mydomain, client2.$mydomain, $myhostname, localhost.$mydomain, localhost, $mydomain, mail.$mydomain
mynetworks = 192.168.64.0/25, 192.168.64.0/24, 127.0.0.0/8
relayhost = [server.example.com]
home_mailbox = Maildir/
mail_spool_directory = /var/spool/mail
PS 所有机器上的防火墙和 selinux 都已关闭。问题是什么？
