我正在为 Postfix 编写一个 Milter，它处理带有虚拟域和用户的服务器（Postfix+Dovecot）中的传入消息。通信 betweend Postfix 和 Milter 使用 Sendmail Milter Protocol V 2 完成
我真的需要 Dovecot（以及由此产生的 Postfix）不会拒绝收件人无效的邮件，因为我需要 Milter 来执行此检查（并拒绝接受）。
这是必需的，因为我正在编写 PEC 邮件服务器（Pec 代表 Posta Elettronica Certificata，这是意大利认证邮件的实现）。
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。
但是在这种情况下，Postfix（由 dovecot 告知）在将邮件发送到 Milter 之前会拒绝该邮件。
我试图在文档中搜索这个，但无法找到这个特定的需求。
我已附加 PostFix 配置....
