11 Razor, Pyzor 및 DCC 설치 및 SpamAssassin 구성

Razor, Pyzor 및 DCC는 협업 필터링 네트워크를 사용하는 스팸 필터입니다. Razor 및 Pyzor를 설치하려면 다음을 실행하십시오.

yum install perl-Razor-Agent pyzor

그런 다음 두 서비스를 초기화합니다:

chmod -R a+rX /usr/share/doc/pyzor-0.4.0 /usr/bin/pyzor /usr/bin/pyzord  
chmod -R a+rX /usr/lib/python2.4/site-packages/pyzor  
su -m amavis -c 'pyzor --homedir /var/spool/amavisd discover'  
su -m amavis -c 'razor-admin -home=/var/spool/amavisd -create'  
su -m amavis -c 'razor-admin -home=/var/spool/amavisd -register'

(첫 번째 시도가 실패하면 마지막 명령을 두 번 실행해야 할 수도 있습니다.)

그런 다음 DCC를 다음과 같이 설치합니다:

cd /tmp  
wget http://www.dcc-servers.net/dcc/source/dcc-dccproc.tar.Z  
tar xzvf dcc-dccproc.tar.Z  
cd dcc-dccproc-1.3.42  
./configure --with-uid=amavis  
make  
make install  
chown -R amavis:amavis /var/dcc  
ln -s /var/dcc/libexec/dccifd /usr/local/bin/dccifd

이제 SpamAssassin에 이 세 프로그램을 사용하도록 지시해야 합니다. /etc/mail/spamassassin/local.cf 파일을 편집하여 다음과 같이 만듭니다:

vi /etc/mail/spamassassin/local.cf

| # 이러한 값은 ~/.spamassassin/user_prefs.cf를 편집하여 재정의할 수 있습니다. # (자세한 내용은 spamassassin(1)을 참조하십시오.) # 이러한 값은 안전한 가정이어야 하며, 잃어버린 이메일의 위험 없이 간단한 시각적 필터링을 허용해야 합니다. #required_hits 5 #report_safe 0 #rewrite_header Subject [SPAM] # dcc use_dcc 1 dcc_path /usr/local/bin/dccproc dcc_add_header 1 dcc_dccifd_path /usr/local/bin/dccifd #pyzor use_pyzor 1 pyzor_path /usr/bin/pyzor pyzor_add_header 1 #razor use_razor2 1 razor_config /var/spool/amavisd/razor-agent.conf #bayes use_bayes 1 use_bayes_rules 1 bayes_auto_learn 1 |

다음으로 실행합니다.

/etc/init.d/amavisd restart

그 후에.

이제 인터넷에서 찾을 수 있는 일부 사용자 정의 규칙 세트를 SpamAssassin에 삽입하고 싶습니다. 나는 그 규칙 세트를 테스트했으며, 스팸 필터링을 훨씬 더 효과적으로 만듭니다. /usr/local/sbin/sa_rules_update.sh 파일을 생성합니다:

vi /usr/local/sbin/sa_rules_update.sh

스크립트를 실행 가능하게 만듭니다:

chmod 755 /usr/local/sbin/sa_rules_update.sh

그런 다음 해당 스크립트를 한 번 실행하면 규칙 세트를 가져와 SpamAssassin에 삽입합니다:

/usr/local/sbin/sa_rules_update.sh

정기적으로 규칙 세트를 업데이트할 수 있도록 크론 작업을 생성합니다. 다음을 실행하십시오:

crontab -e

크론 작업 편집기를 열고 다음 크론 작업을 생성합니다:

| 23 4 */2 * * /usr/local/sbin/sa_rules_update.sh &> /dev/null |

이 작업은 매 2일마다 4시 23분에 규칙 세트를 업데이트합니다.

12 쿼타 초과 알림

모든 이메일 계정이 쿼타를 초과했을 때 알림을 받으려면 다음을 수행하십시오:

cd /usr/local/sbin/  
wget http://puuhis.net/vhcs/quota.txt  
mv quota.txt quota_notify  
chmod 755 quota_notify

/usr/local/sbin/quota_notify 파일을 열고 상단의 변수를 편집합니다:

vi /usr/local/sbin/quota_notify

| my $POSTFIX_CF = "/etc/postfix/main.cf"; my $MAILPROG = "/usr/sbin/sendmail -t"; my $WARNPERCENT = 80; my @POSTMASTERS = ('[email protected]'); my $CONAME = 'ISP.tld'; my $COADDR = '[email protected]'; my $SUADDR = '[email protected]'; my $MAIL_REPORT = 1; my $MAIL_WARNING = 1; |

실행합니다:

crontab -e

해당 스크립트에 대한 크론 작업을 생성합니다:

| 0 0 * * * /usr/local/sbin/quota_notify &> /dev/null |
