Logstash grok 过滤器以标记退回的邮件

Question

摘要：我有一些出站 smtp 服务器，并通过 rsyslog 将邮件日志集中到我正在使用 logstash 的服务器上，输出到 elasticsearch，使用 kibana 进行搜索。

我想将后缀邮件日志条目标记为"退回"，例如：

2013-02-01T16:50:14+02:00 XXSMTPXX postfix/smtp[10879]: BC54A65BD4: to=<[e-mail].t>, relay=none, delay=0.3, delays=0.01/0/0.29/0, dsn=5.4.4, status=bounced (Host or domain name not found. Name service error for name=gozdesigorta.com.t type=AAAA: Host not found)

我在 logstash.conf 中使用的 grok 过滤器是这样的：

grok {
    patterns_dir => "/etc/logstash/patterns"
    tags    => "postfix/bounce"
    pattern => "%{POSTFIXBOUNCE}"
    add_tag => "BOUNCED"
    named_captures_only => true
}

我正在使用的模式文件 https://gist.github.com/4691822

我无法设法将这些日志行标记为退回...我错过了什么？

我将模式更改为：

%{TIMESTAMP_ISO8601} %{HOST} %{SYSLOGPROG}: %{QUEUEID}: to=<%{EMAILADDRESS:to}>, relay=%{RELAY}, delay=%{POSREAL:delay}, delays=%{DELAYS}, dsn=%{DSN}, status=%{STATUS} %{GREEDYDATA:reason}

现在我可以摸索;)

你能粘贴完整的logstash.conf吗？我收到以下错误：
