我正在尝试将 always_bcc 设置为存档帐户，以便将所有入站和出站邮件复制到可由第三方云存档解决方案吸收的邮箱中。出站，工作正常，没有问题。入站，整个系统就崩溃了。发送的所有内容都会保留在 postfix 邮件队列中：

更新：那些 dovecot 命名空间错误或许与我寻求进一步帮助之前尝试过的一些修复有关。我将在周末再次尝试处理这个问题，看看我是否可以在日志中找到任何其他错误或我能找到的任何其他东西来帮助我弄清楚发生了什么。我会在这里更新我发现的任何东西。这个问题特别令人困惑，因为我似乎找不到任何能指引我正确方向的东西。我并不特别习惯在流程的某个阶段没有以错误的形式清晰地出现的软件或配置问题。
答案1
在 etc/postfix/main.cf 文件中添加此行 dovecot_destination_recipient_limit = 1
