不希望 Postfix+Dovecot 拒绝 "recipient not found" 封邮件

Question

我正在为 Postfix 编写 Milter，用于处理服务器 (Postfix+Dovecot) 中带有虚拟域和用户的传入消息。 Postfix 和 Milter 之间的通信是通过 Sendmail Milter Protocol V 2

完成的

我真的需要 Dovecot（以及 Postfix 因此）不拒绝收件人无效的邮件，因为我需要 Milter 来做这个检查（并拒绝 weel）。

这是必需的，因为我正在编写一个 PEC 邮件服务器（Pec 代表 Posta Elettronica Certificata，这是一种用于认证邮件的意大利实现）。

当收到收件人不正确的邮件时，我需要以电子邮件的形式出示特定的收据。

但是 Postfix 在这种情况下（由 dovecot 告知）在将邮件发送到 Milter 之前拒绝邮件。

我试图在文档中搜索此内容，但未能找到此特定需求。

我已附加 PostFix 配置....

我找到了解决方案：

我需要在main.cf

中设置

virtual_mailbox_maps =

并将其留空。
