我在 virtual_alias_maps 中有以下条目：
[email protected]: [email protected]
但是如果我发送电子邮件至[电子邮件保护]，它失败了虚拟邮箱表中的用户未知：
Jun 25 21:53:50 zg-3 postfix/smtpd[6071]: NOQUEUE: reject: RCPT from smtp4.enternet.hu[62.112.192.37]: 550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in virtual mailbox table; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<smtp4.enternet.hu>
如果我发送电子邮件至[电子邮件保护]它运行完美。可能有什么问题？当然，我已经运行了 postmap 来更新 virtual.db，并且还重新启动了 postfix。
这是我的main.cf：

答案1
virtual_alias_maps 不需要冒号，而普通别名需要。因此 virtual_alias_maps 条目正确：
