(http://cpanel.net/) I. Doing backups Following files are need to be saved: /etc/exim.conf /etc/antivirus.exim or system_filter.exim II. Installing DrWEB First, download DrWEB antivirus RPM package from here http://www.sald.com/get.html (http://www.sald.com/get.html) Install it using rpm -Uvh command. For example, for glibc 2.3 use # rpm -Uvh ftp://ftp.drweb.ru/pub/unix/drweb-4.30-glibc.2.3.i586.rpm Start drweb daemon using command # /opt/drweb/drwebd start Now lets take care about automatic antivirus databases updates. Add the following cron job: 00 12 * * * /opt/drweb/update/update.pl III. Installing and configuring DrWEB-Exim Download drweb-exim from http://www.sald.com/get.html Untar tgz archive. For example, tar xzvf drweb-exim-4.29.12-F-linux.tar.gz Now we need to copy drweb-exim files to proper directories. # cp -r drweb-exim/etc/drweb/* /etc/drweb/ # cp -r drweb-exim/opt/drweb/doc/* /opt/drweb/doc/ # cp -r drweb-exim/opt/drweb/drweb-* /opt/drweb/ Edit /etc/drweb/drweb_exim.conf Change AdminMail = postmaster to AdminMail = you@yourdomain.com Lets test how it works so far: # /opt/drweb/drweb-exim --check_only --check_user=drweb All tests should be "passed". IV. Configuring Exim We need to make changes in two files to make drweb and exim work together. First, edit /etc/exim.conf Black are lines which we will need to add. ###### begin exim.conf ######## [skipped] ###################################################################### # Runtime configuration file for Exim # ###################################################################### trusted_users = drweb trusted_groups = drweb [skipped] #!!# message_filter renamed system_filter system_filter = /etc/antivirus.exim message_body_visible = 5000 system_filter_pipe_transport = filter_pipe system_filter_reply_transport = address_reply [skipped] ###################################################################### # TRANSPORTS CONFIGURATION # ###################################################################### # ORDER DOES NOT MATTER # # Only one appropriate transport is called for each delivery. # ###################################################################### # A transport is used only when referenced from a director or a router that # successfully handles an address. # This transport is used for delivering messages over SMTP connections. begin transports filter_pipe: driver = pipe user = drweb group = mail return_fail_output ###### end exim.conf ######## CPanel comes with /etc/antivirus.exim filter file. In clean Exim install it is called system_filter.exim Add the following at the end of the file: ###### begin antivirus.exim ####### # to prevent from mail loop, skip already scanned message if $received_protocol is "drweb-scanned" then finish endif pipe "/opt/drweb/drweb-exim -f $sender_address -- $recipients" finish ###### end antivirus.exim ######## V. Restart Exim and test virus checking Thats it with configuration. Now restart exim: # /etc/rc.d/init.d/exim restart and test your email delivery. If email is not going through, inspect /var/logs/exim_mainlog and /var/logs/exim_paniclog Now take one of those ugly MyDoom worms, attach it to your email message and send it to yourself.
