Procmail：管道到程序，否则返回错误给发件人

  • 772

我正在尝试使用 procmail将某个域的所有消息发送到RT（请求跟踪器）。不过，这更多是关于 .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

}

您看到我的 .procmailrc 文件有问题吗？如果队列存在，它可以正常工作，但在那之后，它只是将邮件发送到 /var/mail/username。我想丢弃电子邮件并返回错误消息。

    老实说，我有一段时间没有使用 procmail，所以如果这不能立即起作用，我深表歉意。

    首先，您拥有的脚本中的嵌套导致了问题，因为它几乎将食谱切成了两半。无论如何它们都不是必需的，所以我删除了它们。我还简化了结构并进行了设置，使其永远不会落入本地邮箱。

    #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/"

: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.

# 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.

* !^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.

    希望有帮助。如果您对其中的任何部分有疑问，请发表评论，我会尽力解释。或者弄清楚如果它不起作用，我是如何搞砸的。
