作为一名Postfix的管理员，维护Postfix的正常运行，并随时排除故障，这是最基本的任务。本文提供了一些我自己写及平时搜集到的脚本和程序，以便实现自动化的维护和操作。包括自动清理日志，分析日志，自动增加用户等等。

Here's my own /etc/periodic/daily/460.status-mail-rejects script,
and yes it needs updating when logging formats change.
This script will not show rejected mail when the client never
returned after a soft (450) error code from the server. I use 450
for non-FQDN HELO hostnames, so that I can whitelist mis-configured
sites that aren't spammers.

一个简单的分析log的脚本

#!/bin/sh # Parses postfix style logs if [ $# -ne 2 ]; then echo "Usage: `basename $0` logfile search-criteria" exit 1 fi TMPLOG="/tmp/`basename $0`.work.$$" MATCHES="/tmp/`basename $0`.matches.$$" LOGFILE="$1" if [ "${LOGFILE}" != "-" -a ! -f ${LOGFILE} ]; then echo "File not found (${LOGFILE})" exit 2 fi if echo ${LOGFILE} │ egrep '\.bz2$' /dev/null 2%26amp;1; then CAT="bunzip2 -c ${LOGFILE}" elif echo ${LOGFILE} │ egrep '\.(Z│gz)$' /dev/null 2%26amp;1; then CAT="gunzip -c ${LOGFILE}" elif [ "${LOGFILE}" = "-" ]; then cat ${TMPLOG}.orig CAT="cat ${TMPLOG}.orig" else CAT="cat ${LOGFILE}" fi shift ${CAT} │ egrep -i "$1" │ \ awk '$9 ~ /^[A-Z0-9][A-Z0-9]*:$/ {print $1 " *" $2 ".*" $9}' ${MATCHES} [ -s ${MATCHES} ] %26amp;%26amp; ${CAT} │ egrep -i -f ${MATCHES} [ -f ${TMPLOG}.orig ] %26amp;%26amp; rm ${TMPLOG}.orig [ -f ${TMPLOG} ] %26amp;%26amp; rm ${TMPLOG} [ -f ${MATCHES} ] %26amp;%26amp; rm ${MATCHES} exit 0
我写的一个简单邮件IN/OUT分析脚本

是参考了Wietse的reject 分析脚本后，得到启发写的，希望对用Postfix的朋友有点帮助。
