qmail+SpamAssassin+maildrop

一 安装SpamAssassin

 

相关perl包可到下载(编译部分略)

 

qmail 与SpamAssassin 结合
在SpamAssassin 3.x 的spamc 目录下编译qmail-spamc

# cc -O -o qmail-spamc qmail-spamc.c

# install -m 755 qmail-spamc /var/qmail/bin

确保qmail-queue，spamc 和spamd 在缺省路径中

# ln -s /var/qmail/bin/qmail-queue /usr/bin/qmail-queue


编辑 /etc/tcp.smtp 如下,使所有的邮件都经过SpamAssassin 处理

127.:allow,RELAYCLIENT=""

:allow,QMAILQUEUE="/var/qmail/bin/qmail-spamc"

更新cdb文件

# qmailctl cdb

这样，所有的邮件都经过SpamAssassin 处理，在邮件信头会加上一些扩展信头X-Spam

用daemontool启动spamd(配置略)

 

改toaster-scripts-0.8.1/spamd.run为:

 

#!/bin/sh exec /usr/bin/spamd -L -x -u vpopmail -s stderr --pidfile /var/run/spamd.pid 2>&1

以后重启SA时用：

kill -HUP `cat /var/run/spamd.pid`

下载Chinese_rules.cf

把该规则放在SpamAssassin存放规则的目录，一般在/usr/share/spamassassin

 

二 配置SpamAssassin的local.cf(/etc/mail/spamassassin/local.cf)

#使用CBL-

header    RCVD_IN_CBLLESS          eval:check_rbl('cblless', 'cblless.anti-spam.org.cn.', '127.0.8.5')
describe  RCVD_IN_CBLLESS          Received via a relay in cblless.anti-spam.org.cn
tflags    RCVD_IN_CBLLESS          net
score     RCVD_IN_CBLLESS          3.5

 

#使用CML
header     RCVD_IN_CML          eval:check_rbl('cml', 'cml.anti-spam.org.cn.', '127.0.8.1')
describe   RCVD_IN_CML          Received via a white list relay in cml.anti-spam.org.cn
tflags     RCVD_IN_CML          net nice
score      RCVD_IN_CML         -20.0

local.cf中相关配置参考Mail_SpamAssassin_Conf.pdf

日志文件在: /var/log/spamd

 

三 配置maildrop

配置.qmail-default文件(/home/vpopmail/domains/test.com/.qmail-default)

/usr/local/bin/maildrop ./.mailfilter

邮件用户不存在时.qmaildefault的弹信功能在.mailfilter中实现

配置.mailfilter文件(/home/vpopmail/domains/test.com/.mailfilter)

import EXT

import HOST

SHELL=/bin/bash

VHOME=`/home/vpopmail/bin/vuserinfo -d `

`test -d $VHOME/Maildir/`

if($RETURNCODE !=0 )

{

echo "用户$EXT@$HOST不存在" EXITCODE=77 exit

}

if($SIZE < 262144 )

{

 exception{

xfilter "/usr/bin/spamc -f -u $EXT@$HOST"

 }

}

else

{

to "$VHOME/Maildir/."

}

if (^X-Spam-Flag: YES/)

{

to "$VHOME/Maildir/.Trash/." EXITCODE=0

}

else

{

to "$VHOME/Maildir/."

}
