Procmail：管道到程序，否则返回错误给发件人

我正在尝试使用 procmail发送所有消息对于某个域逆转录（请求跟踪器）。不过，这更多的是关于 .procmailrc 文件的问题。

这是我当前的.procmailrc 文件：

#Preliminaries
SHELL=/bin/sh               #Use the Bourne shell (check your path!)
MAILDIR=${HOME}        #First check what your mail directory is!
LOGFILE=${MAILDIR}/procmail.log
LOG="--- Logging ${LOGFILE} for ${LOGNAME}, "
VERBOSE=yes
MAILDOMAIN='rt.mydomain.com'
RT_MAILGATE="/opt/rt3/bin/rt-mailgate"
RT_URL="http://rt.mydomain.com/"

LOGABSTRACT=all

### Trying to  process using the rt-mailgate script
:0
{
# the following line extracts the recipient from Received-headers.
# Simply using the To: does not work, as tickets are often created
# by sending a CC/BCC to RT
TO=`formail -c -xReceived: |grep $MAILDOMAIN |sed -e 's/.*for *<*\(.*\)>* *;.*$/\1/'`
QUEUE=`echo $TO| $HOME/get_queue.pl`
ACTION=`echo $TO| $HOME/get_action.pl`
:0 h b w 
|/usr/bin/perl $RT_MAILGATE --queue $QUEUE --action $ACTION --url $RT_URL
}


### Upon failure, I want to send back an error message to the user, saying
###   "Queue does not exist." I took this code from the procmailex manpage.
:0 Wh: no-queue.lock
{
## Reply if error
* !^FROM_DAEMON
* !^X-Loop: [email protected]
| formail -rD 8192 no-queue.cache

  :0 ehc
  |(formail -rI"Precedence: junk" -A"X-Loop: [email protected]" ; \
    echo "The Queue or Action was invalid."; echo "--" \
    ) | $SENDMAIL -oi -t

}

您是否发现我的 .procmailrc 文件存在问题？如果队列存在，它工作正常，但此后，它只会将邮件发送到 /var/mail/username。我想丢弃电子邮件并返回错误消息。

说实话，我已经有一段时间没有使用过 procmail 了，所以如果这不能立即起作用，我深表歉意。

首先，脚本中的嵌套造成了问题，因为它几乎将配方减半。它们反正也没有必要，所以我删除了它们。我还简化了结构并进行了设置，这样它就不会落入本地邮箱。

#Preliminaries
SHELL=/bin/sh               #Use the Bourne shell (check your path!)
MAILDIR=${HOME}        #First check what your mail directory is!
LOGFILE=${MAILDIR}/procmail.log
LOG="--- Logging ${LOGFILE} for ${LOGNAME}, "
VERBOSE=yes
MAILDOMAIN='\(help\|rt\)\.\(ncom\|networklubbock\)\.com'
RT_MAILGATE="/opt/rt3/bin/rt-mailgate"
RT_URL="http://rt.ncom.com/"

TO=`formail -c -xReceived: |grep $MAILDOMAIN |sed -e 's/.*for *<*\(.*\)>* *;.*$/\1/'`

ACTION=`echo $TO| $HOME/get_action.pl`
:0w 
|/usr/bin/perl $RT_MAILGATE --queue $QUEUE --action $ACTION --url $RT_URL

# the formail command below looks at the message sender and basically
# swallows the message if it's seen the sender before.  The number
# is the size of the cache file of seen addresses.  A lock file is
# used because multiple formail processes editing that cache will
# corrupt it.

###   "Queue does not exist." I took this code from the procmailex manpage.
# Don't send if this was a bounce from a mailer, and don't send if this
# message contains the header put there to indicate a loop.
:0
* !^FROM_DAEMON
* !^X-Loop: [email protected]
|(formail -rI"Precedence: junk" -A"X-Loop: [email protected]" ; \
  echo "The Queue or Action was invalid."; echo "--" \
  ) | $SENDMAIL -oi -t

# trash anything that falls all the way through.  This should only ever
# happen if the message was a bounce or if it was a loop.

希望这能有所帮助。如果您对其中任何部分有疑问，请发表评论，我会尽力解释。或者如果它不起作用，请弄清楚我是怎么搞砸的。
