postfix安装以及配置8

十、安装amavisd-new-2.6.1(是一个连接MTA和内容检测工具)

1、依赖关系的解决

以下为官方声明所必须的软件包列表，你可以采用类同安装Spamassassin一节中的perl模块的安装方法进行安装

Archive::Zip (Archive-Zip-x.xx) (1.14 or later should be used!)

Compress::Zlib (Compress-Zlib-x.xx) (1.35 or later)

Convert::TNEF (Convert-TNEF-x.xx)

Convert::UUlib (Convert-UUlib-x.xxx) (1.08 or later, stick to new versions!)

MIME::Base64 (MIME-Base64-x.xx)

MIME::Parser (MIME-Tools-x.xxxx) (latest version from CPAN - currently 5.420)

Mail::Internet (MailTools-1.58 or later have workarounds for Perl 5.8.0 bugs)

Net::Server (Net-Server-x.xx) (version 0.88 finally does setuid right)

Digest::MD5 (Digest-MD5-x.xx) (2.22 or later)

IO::Stringy (IO-stringy-x.xxx)

Time::HiRes (Time-HiRes-x.xx) (use 1.49 or later, older can cause problems)

Unix::Syslog (Unix-Syslog-x.xxx)

BerkeleyDB

Crypt::OpenSSL::RSA

Mail::DKIM::Verifier

2、安装amavisd-new-2.6.1

（1）创建运行时目录，并赋予amavis用户（前文中所建）

#mkdir -pv /var/amavis/{tmp,var,db,home}

#chown -R amavis:amavis /var/amavis

#chmod -R 777 /var/amavis

 

（2）解压amavisd

#tar zxvf amavisd-new-2.6.1.tar.gz

#cd amavisd-new-2.6.1

 

（3）拷贝服务端至$PATH中指定的目录，推荐拷贝至/usr/local/sbin：

#cp amavisd /usr/local/sbin/

#chown root /usr/local/sbin/amavisd

#chmod 755 /usr/local/sbin/amavisd

 

（4）拷贝主配置文件至/etc，并修改相应的权限：

#cp amavisd.conf /etc

#chown root:amavis /etc/amavisd.conf

#chmod 640 /etc/amavisd.conf

 

（5）创建amavisd运行中所需要的隔离区域：

#mkdir -v /var/virusmails

     #chown amavis:amavis /var/virusmails/

#chmod 777 /var/virusmails/

3、编辑主配置文件

（1）#vi /etc/amavisd.conf

确保您的如下选项的值如下文所示：

$daemon_user = 'amavis';

$daemon_group = 'amavis';

$mydomain = 'lixin.org';     // 此处可更改为您集体的域

$virus_admin = "postmaster\@$mydomain";

$mailfrom_notify_admin = "postmaster\@$mydomain";

$mailfrom_notify_recip = "postmaster\@$mydomain";

$mailfrom_notify_spamadmin = "postmaster\@$mydomain";

$mailfrom_to_quarantine = '';

virus_admin_maps => ["postmaster\@$mydomain"]  // 指定报告病毒和垃圾邮件时发送系统邮件的用户身份

spam_admin_maps => ["postmaster\@$mydomain"]

DetectPUA yes                                 // 去掉前面的注释

 

启用ClamAV,(大概在第363行)去掉如下行前的注释符:

#['ClamAV-clamd',

# \&ask_daemon, ["CONTSCAN {}\n", " /var/run/clamav/clamd "],

# qr/\bOK$/, qr/\bFOUND$/,

# qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],

# ['Mail::ClamAV', \&ask_clamav, "*", [0], [1], qr/^INFECTED: (.+)/],

并将如上行中的/var/run/clamav/clamd 修改为: /var/run/clamav/clamd.socket （364行

）

4. 安装配置BerkeleyDB（可以不装,建议安装）

（1）安装

#tar zxvf db-4.5.20.tar.gz

#cd db-4.5.20/build_unix

#../dist/configure  --prefix=/usr/local/BerkeleyDB

#make

#make install

 

（2）配置

修改相应的头文件指向

     #mv /usr/include/db4/  /usr/inculde/db4.OFF

#rm /usr/include/db_cxx.h

#rm /usr/include/db.h

#rm /usr/include/db_185.h

#ln -sv /usr/local/BerkeleyDB/include /usr/include/db4

#ln -sv /usr/local/BerkeleyDB/include/db.h /usr/include/db.h

      #ln -sv /usr/local/BerkeleyDB/include/db_cxx.h /usr/include/db_cxx.h

 

配置库文件搜索路径

echo "/usr/local/BerkeleyDB/lib" >> /etc/ld.so.conf

ldconfig �Cv

5、测试启动amavisd

您也可以按如下命令调试启动

/usr/local/sbin/amavisd debug

6、将amavisd注册为系统服务

(1)#cd /srv/amavisd-new-2.6.1

#cp amavisd_init.sh /etc/init.d/amavisd

#chmod +x /etc/init.d/amavisd

 

(2) 修改执行路径

         #vi /etc/rc.d/init.d/amavisd

prog="/usr/local/sbin/amavisd"

 

(3) 注册服务并启动

#chkconfig --add amavisd

#chkconfig --levels 35 amavisd on

#service amavisd start
