1、2022年构建反病毒反垃圾邮件系统(五)邮件服务器教程摘要：暂无二、防病毒系统1、安装McAfee uvscan for linuxMcAfee uvscan for linux虽然是试用，但是没有什么限制，可以升级，也没有过期。# wget http:/www.XXXX.com/products/evaluation/virusscan/english/cmdline/linux/version_4.24/intel/vlnx424e.tar.Z# tar xzf vlnx424e.tar.Z# ./install-uvscan默认会装到/usr/local/uvscan书目下，不过uvsc

2、an须要libstdc+.so.2.8，干脆运行出现如下错误：# uvscanuvscan: error while loading shared libraries: libstdc+.so.2.8:cannot open shared objectfile: No such file or directory可以从如下地址获得libstdc+.so.2.8的安装包：# wget http:/debian.marlow.dk/dists/woody/virus/pool/lib/libstdc+2.8_2.90.29-2.deb# dpkg -i libstdc+2.8_2.90.29-2.

3、deb这样uvscan就可以正常运行了，不过会提示病毒库比较老了云云。写个病毒库更新脚本扔到crontab跑去吧：#!/bin/sh# update-dat.sh#cd /usr/local/uvscan/wget -q -O readme.txt http:/http:/www.XXXX.com/products/datfiles/4.x/nai/readme.txt >/dev/nullAVVER=head -5 readme.txt | grep 40-90-90-9 | head -1 |sed -e s/.* (40-9*) .*$/1/if ! -f dat-$

4、;AVVER.tar ; thenfor i in *.tar ; domv $i $i.olddoneif wget http:/http:/www.XXXX.com/products/datfiles/4.x/nai/dat-$AVVER.tar >/dev/null ; thenfor i in *.dat ; docp -p $i $i.bakdoneif tar xf dat-$AVVER.tar ; thenrm -f *.oldecho date Successfully updated AntiVirus DAT files

5、 to $AVVERfififi2、AMaViS的安装AMaViS是uvscan和postfix之间的一个桥梁，完成邮件解码，交给uvscan查毒，然后再处理，转发操作。安装amavisd前先确定以下软件已经安装，lha、unarj等运用的no-free的分支版本：# apt-get install libio-stringy-perl mailtools libmime-perl libmailtools-perl libmime-base64-perl libcompress-zlib-perl libconvert-uulib-perl libconvert-tnef-perl

6、tnef libarchive-tar-perl libarchive-zip-perl libtime-hires-perl libunix-syslog-perl libdigest-md5-perl lha unarj unzip gzip unrar zoostable版本的amavisd比较老，运用如下链接：# wget http:/www.XXXX.dk/dists/woody/custom/pool/compress/arc_5.21e-5_i386.deb# wget http:/www.XXXX.dk/dists/woody/virus/pool/wrapper/amavis

7、d-new_20220314p1-2_all.deb# wget http:/www.XXXX.dk/dists/woody/virus/pool/lib/libnet-perl_1.12-1_all.deb# wget http:/www.XXXX.dk/dists/woody/virus/pool/lib/libnet-server-perl_0.84-3_all.deb先安装CPAN：# perl -MCPAN -e shellcpan> install CPANcpan> install LWPcpan> install Archive:Tarcpan> ins
