一些信息：
example.com has a MX-record with priority 10,20 and 30 to mail.example.com mail.example.com has an A-record to 192.0.2.0 (fictional ip) 这是我的postfix的main.cf

这是我收到的错误：
Technical details of temporary failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain example.be by mail.example.com. [192.0.2.0].
任何想法，我应该改变，以使mailforwarding工作？ （我已经在Postfix目录中的“虚拟”文件中configuration了转发邮件（例如hotmail.com）
这里是在虚拟中使用的线
[email protected] [email protected] [email protected] [email protected]
更新1：对不起，我刚刚看到你已经定义了virtual_alias_domains 。 这个文件的内容是什么？
$mydomain在哪里？
你需要告诉postfix你接受邮件的域名。
mydestination = $myhostname localhost.$mydomain localhost $mydomain
请注意，您的configuration在mydestination参数中不显示$mydomain 。
在你的main.cf中，包含以下内容：
mydomain = example.com mydestination = $myhostname localhost.$mydomain localhost $mydomain
另外，请不要使用Google的DNS作为您的示例IP。 这真的很让人困惑，特别是如果您通过从Gmail.com发送邮件进行testing
一个更好的testing是简单地打开一个telnet会话到邮件服务器的25端口，然后在那里手动inputSMTP命令。 （您可以在网上find大量的指南来远程login和排除SMTP故障）。
Update2 – 为你的例子使用保留的地址 – 6.6.6.6也是一个真实的地址。
根据RFC 5737 ，
文档中提供了192.0.2.0/24（TEST-NET-1），198.51.100.0/24（TEST-NET-2）和203.0.113.0/24（TEST-NET-3）块。
