我搜索了几个小时却没有找到解决方案，这让我发疯了。
是否可以在不使用 Procmail 的情况下确保 Postfix 以 Maildir 的形式发送电子邮件{cur,new,tmp}？
/var/spool/mail/$USER如何做到？
我有mail_spool_directory = /var/spool/mail，但是它把我扔掉了，因为它想在那里创建一个邮箱，并且它在那里找到了一个目录：
(cannot update mailbox /var/spool/mail/regine for user regine. cannot open file: Is a directory)
如果我添加home_mailbox = ./或home_mailbox = /，邮件将以 Maildir 格式传递，但在 中/home/regine/{cur,new,tmp}。
我怎样才能拥有相同的 Maildir 格式/var/spool/mail/USER/？

如果希望 postfix 使用 Maildirs，则必须在 mail_spool_directory 配置值的末尾添加一个斜杠。否则它将使用 mbox 样式的传递。
因此，在您的情况下，您需要将 mail_spool_directory 的值更改为mail_spool_directory = /var/spool/mail/。
