8 Razor, Pyzor 및 DCC 설치 및 SpamAssassin 구성

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

apt-get install razor pyzor dcc-client

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

| # This is the right place to customize your installation of SpamAssassin. # # See 'perldoc Mail::SpamAssassin::Conf' for details of what can be # tweaked. # ########################################################################### # # rewrite_header Subject ***SPAM*** # report_safe 1 # trusted_networks 212.17.35. # lock_method flock # dcc use_dcc 1 dcc_path /usr/bin/dccproc dcc_add_header 1 dcc_dccifd_path /usr/sbin/dccifd #pyzor use_pyzor 1 pyzor_path /usr/bin/pyzor pyzor_add_header 1 #razor use_razor2 1 razor_config /etc/razor/razor-agent.conf #bayes use_bayes 1 use_bayes_rules 1 bayes_auto_learn 1 |

그 후에

/etc/init.d/amavis restart

를 실행하십시오.

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

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 이러한 규칙 세트를 업데이트하기 위해 cron 작업을 생성합니다. 다음을 실행하십시오:

crontab -e

cron 작업 편집기를 열기 위해. 다음 cron 작업을 생성하십시오:

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

이렇게 하면 매 2일마다 4시 23분에 규칙 세트가 업데이트됩니다.

(참고 (조금 주제에서 벗어남): Debian Sarge에서 crontab -e는 자동으로 편집기 nano를 엽니다. vi 편집기로 작업하는 데 익숙하다면 (저처럼), 다음 명령을 실행하십시오:

rm -f /etc/alternatives/editor
ln -s /usr/bin/vi /etc/alternatives/editor

그 후 crontab -e를 실행하면 vi가 나타납니다.)

9 쿼타 초과 알림

모든 이메일 계정의 쿼타 초과에 대한 알림을 받고 싶다면 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_notify를 열고 상단의 변수를 편집하십시오:

| 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; |

다음으로

crontab -e

를 실행하여 해당 스크립트에 대한 cron 작업을 생성하십시오:

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