Рабочая конфигурация : amavisd-new-2.1.2 + clamav-0.80 стоит у меня на freebsd 4.9 2) cd /usr/ports/security/amavisd-new/ делаем make, если ругается на perl, идём в /usr/ports/lang/perl5.8 делаем make install если всё поставилось без вопросов, тогда идём в cd /work делаем файл use.perl запускным, после чего запускаем - ./use.perl port Теперь у нас есть perl линейки 5.8 и он анонсирован в системе как дефолтный. Идём опять в /usr/ports/security/amavisd-new/ И делаем : make после чего идём в папку cd /work/amavisd-new-2.1.2 и делаем следующее : patch <amavisd-new-qmqpqq.patch Далее : make install Это мы поставили приблуду которая свяжет нам спамфильтр и антивирус (поддерживает около 10-ти антивирусных систем, можно включить все сразу, "для параноиков" 8-))) ). 3) Ставим спамфильтр - cd /usr/ports/mail/p5-Mail-SpamAssassin/ make make install 4) Ставим антивирус cd /usr/ports/security/clamav/ make make install 5) Нам нужно пропатчить наш qmail, ищем папку с исходниками qmail-а, если таковой уже давно нет, тогда идём на http://www.opennet.dev/base/net/qmail_antispam.txt.html и качаем по ссылкам qmail и все нужные патчи к нему, плюс тот что нужен нам можно найти здесь - http://www.imladris.sk/howto/download/qmail-queue.patch Далее патчим qmail всеми патчами. Идём в каталог с qmail-ом, находим файл qmail-qmqpc.c и меняем в нем #define PORT_QMQP 628 на #define PORT_QMQP 10628 Устанавливаем qmail туда же где он уже стоит. Настройка программного обеспечения: ------------------------------------ 1) Идём туда где у нас лежит файл с адресами которым разрешен "открытый релей", у меня такой файл лежит в /etc называется tcp.smtp, в него нужно добавить строчку: 127.10.10.10:allow,RELAYCLIENT="",QMAILQUEUE="bin/qmail-queue.orig" Далее нужно создать файл tcp.smtp.amavis и сунуть в него следующее : 127.10.10.10:allow,RELAYCLIENT="",QMAILQUEUE="bin/qmail-queue.orig":deny А в файл ренегации базы добавить строчку : tcprules /etc/tcp.smtp.amavis.cdb /etc/tcp.smtp.amavis.tmp < /etc/tcp.smtp.amavis В файл запуска tcpserver-ов добавляем : tcpserver -x /etc/tcp.smtp.amavis.cdb -p -DRHl localhost -u 89 -g 83 127.10.10.10 10025 \ /var/qmail/bin/qmail-smtpd & В моем случае - -u 89 : это uid пользователя vpopmail -u 83 : это gid группы vchkpw 2) В папке /var/qmail/control создать файл qmqpservers и сунуть в него: 127.10.10.10 3) Нам нужен алиал ip на локальном интерфэйсе, для этого запускаем команду: ifconfig lo0 inet 127.10.10.10 netmask 255.255.255.255 alias И дописываем в /etc/rc.conf : ifconfig_lo0_alias0="inet 127.10.10.10 netmask 255.255.255.255" 4) Привожу свой конфигурационный файл от amavisd-new (в нём только нужно указать ваш дефолтный домен), лежит он /usr/local/etc/amavisd.conf:

Привожу свой конфигурационный файл от антивируса clamd - /usr/local/etc/clamd.conf :

## ## Example config file for the Clam AV daemon ## Please read the clamd.conf(5) manual before editing this file. ## # Comment or remove the line below. #Example # Uncomment this option to enable logging. # LogFile must be writable for the user running daemon. # A full path is required. # Default: disabled LogFile /var/log/clamav/clamd.log # By default the log file is locked for writing - the lock protects against # running clamd multiple times (if want to run another clamd, please # copy the configuration file, change the LogFile variable, and run # the daemon with --config-file option). # This option disables log file locking. # Default: disabled #LogFileUnlock # Maximal size of the log file. # Value of 0 disables the limit. # You may use 'M' or 'm' for megabytes (1M = 1m = 1048576 bytes) # and 'K' or 'k' for kilobytes (1K = 1k = 1024 bytes). To specify the size # in bytes just don't use modifiers. # Default: 1M #LogFileMaxSize 2M # Log time with each message. # Default: disabled LogTime # Also log clean files.

5) Идём в папку /usr/local/etc/rc.d, нужно немного подредактировать запускные файлы amavisd.sh, clamav-clamd.sh и clamav-freshclam.sh, в них во всех нужно заскоментировать строчки : в amavisd.sh: amavisd_enable="YES" в clamav-clamd.sh: clamav_clamd_enable="YES" в clamav-freshclam.sh: clamav_freshclam_enable="YES" Теперь всё готово к запуску, НО, всё же ещё рано, нужно занести пользователя clamav в группу vscan, для этого идём в /etc и открываем файл group, дописываем clamav в группу vscan и должно получится что-то вроде : vscan:*:1002:clamav Теперь наверное всё. Идём в /usr/local/etc/rc.d и запускаем файлы amavisd.sh, clamav-clamd.sh и clamav-freshclam.sh. Смотри процессы ps ax, если всё запустилось нормально, в списке должны быть : 162 ?? Ss 0:10.66 amavisd (master) (perl) 190 ?? Ss 1:32.63 /usr/local/sbin/clamd 197 ?? Is 0:00.18 /usr/local/bin/freshclam -daemon 22326 ?? S 1:17.30 amavisd (ch331-avail) (perl) 22555 ?? S 1:15.20 amavisd (ch327-avail) (perl) 22668 ?? S 1:11.71 amavisd (ch329-avail) (perl) 22723 ?? S 1:09.37 amavisd (ch325-avail) (perl) 22742 ?? S 1:13.26 amavisd (ch325-avail) (perl) 22770 ?? S 1:13.80 amavisd (ch326-avail) (perl) 22803 ?? S 1:15.35 amavisd (ch324-avail) (perl) 22944 ?? R 1:09.06 amavisd (22944-323) (perl) 23023 ?? S 1:10.89 amavisd (ch320-avail) (perl) 23036 ?? S 1:12.03 amavisd (ch324-avail) (perl) Если всё это есть и amavisd запустился без ошибок, тогда нам остается на пару секунд зашатдаунить qmail для того чтобы сделать пару заключительных команд : cd /var/qmail/bin mv qmail-queue qmail-queue.orig ln -s qmail-qmqpc qmail-queue после чего запускаем qmail и наслаждаемся. Всю информацию по пойманным вирусам и спаму читать в /var/amavis/amavis.log

Вообще-то правильно будет

:deny

в две строчки: разрешаем для 127.10.10.10 и запрещаем для всех остальных
