我按照本教程设置了一个使用虚拟用户的电子邮件服务器。https://www.rosehosting.com/blog/mailserver-with-virtual-users-and-domains-using-postfix-and-dovecot-on-a-centos-6-vps/
我可以发送电子邮件，但是当我尝试向其中一个虚拟邮箱发送电子邮件时，邮件日志中出现以下错误。
收件人地址被拒绝：虚拟邮箱表中的用户未知；
根据我所做的研究，似乎这一行就是原因。具体来说就是“reject_unauth_destination”。
> smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated, reject_unauth_destination
我尝试删除“reject_unauth_destination”值，然后出现以下错误。
致命：在参数 smtpd_relay_restrictions 或 smtpd_recipient_restrictions 中，指定至少一个工作实例：reject_unauth_destination、defer_unauth_destination、reject、defer、defer_if_permit 或 check_relay_domains
有人知道我该怎么做才能修复这个错误吗？我可以正常登录帐户并发送邮件。除了拒绝电子邮件之外，一切似乎都很好。

我已在 3 个 vmail 文件中添加了记录来配置账户
vmail_domains - mydomain.com OK
vmail_mailbox - [email protected] mydomain.com/dan/
vmail_aliases - [email protected] [email protected]
答案1
错误很明显，你用过postmap吗？试试。postmap -q [email protected] hash:/etc/postfix/vmail_mailbox
为了解决你的问题你需要使用"postmap /etc/postfix/vmail_mailbox and service postfix"
如果您在 Postfix 中使用哈希表，则每次更改文本文件时都需要在文件上使用 postmap 来重新生成 db 文件。
