Amavisd安装配置

安装amavisd

Shell> tar xvf amavisd-new-2.9.0.tar.xz

Shell> cd amavisd-new-2.9.0

Amavisd和Spamassassin安装需要很多perl module，安装之间先看下INSTALL文件，源码安装太麻烦，如果有联网建议CPAN安装

INSTALL列出先决条件如下：

Perl 模块如下

邮件病毒扫描需求（已经安装）

扩展程序（暂时不安装）

第三方工具（暂时不安装）

Shell> perl �CMCAPN �Ce shell

Cpan> install Archive::Zip

Cpan> install Compress::Zlib

Cpan> install Compress::Raw::Zlib

Cpan> install MIME::Base64

Cpan> install MIME::Parser

Cpan> install Mail::Internet

Cpan> install Net::Server

Cpan> install Digest::MD5

Cpan> install Time::HiRes

Cpan> install Unix::Syslog

Cpan> install Mail::DKIM

Cpan> install IO::Stringy

Cpan> install Convert::BinHex

Cpan> install BerkeleyDB

Cpan> install Unix::Getrusage

cpan> install Image::Info

 

amavisd配置

shell> vi /etc/amavisd.conf

$daemon_user = 'amavis';

$daemon_group = 'amavis';

$mydomain = 'zhengwing.org';

$MYHOME = '/var/amavis';

$TEMPBASE = "$MYHOME/tmp";.

$QUARANTINEDIR = '/var/amavis/var/virusmails';

$db_home = "$MYHOME/db";

$helpers_home = "$MYHOME/home";

$lock_file = "$MYHOME/var/amavisd.lock";

$pid_file = "$MYHOME/var/amavisd.pid";

$unix_socketname = "$MYHOME/var/amavisd.sock";

$myhostname = 'mail.zhengwing.org';

##以上是amavisd.conf基本配置

##以下是amavisd.conf关于clamav配置

['ClamAV-clamd-stream',

\&ask_daemon, ["*", 'clamd:/data/sw/clamav/run/clamd.sock'],

qr/\bOK$/m, qr/\bFOUND$/m,

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

 

Postfix支持amavisd

Shell> vi /etc/postfix/master.cf

Shell> postfix reload

调试

Shell> /usr/local/sbin/amavisd �Cu amavis debug

如果有问题，参照调试日志修改

启动
