Dovecot 忽略了筛子

Question

我的电子邮件服务器中安装了典型的 postfix+dovecot。使用 Roundcube 作为网络邮件，一切正常。问题是，显然已激活的筛选插件不起作用，或者诸如此类。因为我有不起作用的筛选规则。以下是.dovecot.sieve我的用户的评论：

require ["fileinto","regex"];
# rule:[Spam]
if anyof (header :regex "from" ".*@163.com", header :contains "from" "[email protected]", header :regex "from" ".*@126.com")
{
        discard;
}
# rule:[Parabola-assist]
if allof (header :contains "to" "[email protected]")
{
        fileinto "Maildir/.INBOX.Parabola-Assist";
        stop;
}
# rule:[Parabola-issues]
if allof (header :contains "from" "[email protected]")
{
        fileinto "Maildir/.INBOX.Parabola-Issues";
}
# rule:[Parabola-dev]
if allof (header :contains "to" "[email protected]")
{
        fileinto "Maildir/.INBOX.Parabola-Dev";
}
# rule:[Test]
if allof (header :contains "from" "[email protected]")
{
        fileinto "Maildir/.INBOX.Parabola-Dev";
        stop;
}

在所有情况下，我都尝试了不同的目录，例如省略 Maildir/、不带点的 .INBOX 文件夹等，但结果相同。最糟糕的是日志中什么都没有 :S

这是我的 Dovecot 配置：
