mysql - 别名不起作用

Question

我正在尝试使用 postfix 和 dovecot 设置邮件服务器，但是由于某些原因我无法使用别名。每次我向别名发送邮件时，我都会收到“用户未知”或“虚拟邮箱表中的用户未知”。我使用了 postmap -q alias@example.com mysql:/etc/postfix/mysql-virtual-alias-maps.cf 并返回 user@example.com正如预期的那样。我还在 mysql 中启用了查询日志记录，我可以看到查询已执行，但出于某种原因，它仍会检查用户 alias@example.com 是否存在，当然它不存在。

Answer 1

找到解决方案，显然 receive_override_options = no_address_mappings 禁用虚拟别名，所以当我删除该行时，一切都开始按预期工作。
