维护Postfix的一些脚本、程序集锦

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.

#!/bin/sh

echo ""; echo "Scanning maillog for rejections:"
zcat -fc /var/log/maillog.0* /var/log/maillog | egrep reject: | cut -d : -f 5- | sort | uniq -c | sort -nr | grep -v '^ *[1-2] *[^ ]* [^ ]* from [^ ]*: 450 '

echo "";
echo "Scanning maillog for warnings:"
zcat -fc /var/log/maillog.0* /var/log/maillog | egrep warning: | cut -d : -f 5- | sort | uniq -c

print "";
echo "Scanning maillog for trouble:"
zcat -fc /var/log/maillog.0* /var/log/maillog | egrep '(fatal|panic):'

一个简单的分析log的脚本
Author: Michael Tokarev

#!/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>&1; then
CAT="bunzip2 -c ${LOGFILE}"
elif echo ${LOGFILE} │ egrep '\.(Z│gz)$' >/dev/null 2>&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} ] && ${CAT} │ egrep -i -f ${MATCHES}

[ -f ${TMPLOG}.orig ] && rm ${TMPLOG}.orig
[ -f ${TMPLOG} ] && rm ${TMPLOG}
[ -f ${MATCHES} ] && rm ${MATCHES}

exit 0

我写的一个简单邮件IN/OUT分析脚本
Author: hzqbbc

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。

#!/bin/bash
# mail-statistic.sh :
# Simple script for analysis Postfix maillog
# Version: 0.03
# Author: [email protected]
#

RAN=`echo $RANDOM`
echo "Mail log analysis ID is $RAN "
echo "Checking ...................."
echo ""
echo ""
# make a direcotry to contain temp log file
mkdir $RAN
cp /var/log/maillog $RAN/maillog
zcat /var/log/maillog.*.gz >> $RAN/maillog

# statistic recipient
echo "Part one : - Top 10 Recipient domain "
fgrep to= $RAN/maillog | cut -d\< -f2 | cut -d\> -f1 | cut -d@ -f2 | sort | uniq -c | sort -nr |head
echo ""
echo ""

# statistic sender
echo "Part two: - Top 10 Sender domain "
fgrep from= $RAN/maillog | cut -d\< -f2 | cut -d\> -f1 | \
cut -d@ -f2 | sort | uniq -c | sort -nr | head
echo ""
echo ""

# statistic destination mail total count
echo "Part three: Total lines and sizes of log, And total mail sent"
echo "Log_lines = `cat $RAN/maillog | wc -l | awk '{ print $1 }'`"
echo "Log_sizes = `du -s $RAN/maillog | awk '{ print $1}'`"
echo "Mail_sent = `cat $RAN/maillog | fgrep status=sent | wc -l | \
awk '{ print $1 }'`"
rm -rf $RAN
