邮箱中新文件的Postfix / Dovecot权限

根据这篇文章 ：

在邮箱内创build新文件时，Dovecot从邮箱目录复制读写权限。

我没有看到这个 这是我所看到的：

邮件目录有rw的组，并且由于某种原因，新目录中的单个文件没有rw。 正因为如此，他们不能被他们希望被访问的人/进程访问。 我错过了什么？

• 后缀 – 不同的头检查传入和传出的邮件
• Postfix什么时候像客户端一样行事？
• 在dovecot imap服务器上发送邮件文件夹的最佳做法
• 后缀连接超时
• 如何停止从发件人在postfix中的双反弹

我正在运行的Ubuntu 12.04LTS

更新1

给一些背景：我已经运行了很长一段时间的postfix + dovecot。 根据这个文件安装了一些小的偏差。 通常邮箱不是本地访问，我通过远程客户端通过POP / IMAP访问。

但是我觉得在服务器上偶尔运行mutt会很有用。 如果我运行它，我可以做到

 sudo mutt -f /var/mail/vhosts/myhost.com/andrews 

但是我想能够在没有 sudo的情况下运行，这就是麻烦的起因。 我将myslef添加到vmail组中，并将以下行添加到.muttrc中：

 set spoolfile = '/var/mail/vhosts/myhost.com/andrews/' alternates myhost.com set reverse_name = yes set from = '[email protected]' 

但是这不起作用，除非我明确地对new和cur进行chmod g + rw。 它只有在新邮件到达之前才起作用，因为新邮件没有这个rw。

无论如何，我可以解决这个问题吗？

在和NickW讨论这个问题后，我们得出结论，实际上Postfix是在写这些文件，而不是Dovecot。 LDA很可能是Postfix虚拟的 。 这是Postfixconfiguration。

我search了Postfix的文档，我无法find一个方法来指定邮箱内新build邮件文件的Postfix权限。

我的想法是，这可能是不可能的，然后必须有另一种方式设置mutt，以便它可以访问maildirs，而不需要做sudo /根。

任何提示都表示赞赏。
