我正在尝试设置 postfix、dovecot 和 procmail 以便与虚拟用户一起工作。最后，我希望拥有虚拟用户以及添加规则以对传入规则进行排序的可能性。最后一件事，我需要 procmail（对吗？）。
当我向我的服务器发送电子邮件时，我没有在 Maildir 中收到它，并且在 mail.log 中看到以下内容：

如何修复 procmail 吐出的“拒绝特殊权限”行？
camilstaps@cs:/# ls -al /etc/procmailrcs

我使用的是 Ubuntu 服务器 13.04。
答案1
man procmail状态：
Denying special privileges for "x"
Procmail will not take on the identity that comes with the rcfile because
a security violation was found (e.g. -p or variable assignments on the
command line) or procmail had insufficient privileges to do so.
在所呈现的情况下，错误消息是由variable assignments on the command line例如引起的E_SENDER=$sender。
可能的修复：
使用另一个“非 procmail 特殊”目录来存储脚本而不是 /etc/procmailrcs
（据我所知，在这种情况下不需要 /etc/procmailrcs 魔法）
或者
在命令行上传递使用位置参数并在 *.rc 文件中分配
procmail 脚本调用：
/usr/bin/procmail -m /etc/procmailrcs/default.rc $sender $recipient $user $domain $extension $nexthop
procmail 脚本（初始部分）：
# DROPRIVS - procmail magical variable, assigment causes side effects
DROPPRIVS=yes
E_SENDER=$1
E_RECIPIENT=$2
ER_USER=$3
ER_DOMAIN=$4
ER_DETAIL=$5
NEXTHOP=$6
