A: It's a mail filter for MTAa and MDAs. It filters mail traffic for a virus infection. Q: What isn't avastfilter? A: It's not a mail router. It examines messages for an infected code and rejects or accept them to be relayed next only. Q: Why to install avast4mail? A: This software prevents spreading of viruses inside and outside your network. Q: Does avast4mail require avast4server package to be installed? A: Yes, avast! daemon performs all scanning jobs for avastfilter. Q: avastmilter doesn't catch viruses, what should I do? A: check this: - avastmail and avast4server is installed and properly configured - libavastengine has valid and non-expired license file - MIME packer is set in avastd.conf file - Avast4TempDir directory specified in avastengine.conf file has 1777 permissons avast4mail-3.2.1-i586/INSTALL0000644000000000000000000003644111401233054015243 0ustar rootroot00000000000000 avast4mail - version 3.2.1 Copyright (C) 2005-2010 by ALWIL Software. All rights reserved. INTRODUCTION: ============= This program is a SMTP filter that allows you to check mail messages for virus infections using the avast! Antivirus. Every e-mail is scanned before forwarding. Currently the filter works well with Postfix, Sendmail, Qmail, Exim, maildrop, procmail and getmail, but the filter should work with other MTA/MDAs. INSTALLATION REQUIREMENTS: ========================== It is assumed that you have some supported MTA/MDA and avast! antivirus daemon installed. It's also required to be logged as system administrator. To compile/install avastfilter you need to have a fairly recent version of a (GNU) C compiler and GNU autotools. This package has been compiled and tested on Linux, BSD and Solaris systems, but it should work on any existing POSIX compatible system. If you manage to successfully test it on any other system, please contact the author. BUILD AND INSTALL AVAST4FILTER: =============================== If you have downloaded and installed a binary distribution of avast4mail, then there's no need to read the following instructions. Please continue with the next section! If you have downloaded a compressed source code archive, then please proceed the usual procedure to build and install avast4mail: check the configure options: ./configure --help % ./configure --prefix=/usr % make % make install This should install avastfilter program. After installing, please create avmail user and group names: LINUX: (if /bin/false file doesn't exist, please set /sbin/nologin instead!) % groupadd avmail % useradd -c avastmail -d /var/lib/avastmail -s /bin/false -g avmail avmail SOLARIS: % groupadd avmail % useradd -c avastmail -d /var/lib/avastmail -s /bin/false -g avmail avmail BSD: % pw groupadd -n avmail % pw useradd -c avastmail -d /var/lib/avastmail -s /sbin/nologin -g avmail -n avmail It's required to set the owner and permissions of /usr/bin/avastfilter and /var/run/avastmail and /var/lib/avastmail/tmp directories: % chown root:avmail /usr/bin/avastfilter % chmod 2711 /usr/bin/avastfilter % chown avmail:avmail /var/run/avastmail % chmod 0750 /var/run/avastmail % chown avmail:avmail /var/lib/avastmail/tmp % chmod 1770 /var/lib/avastmail/tmp LIST OF INSTALLED FILES AND DIRECTORIES: ======================================== /etc/mail/avastfilter.conf /usr/bin/avastfilter /usr/share/man/man1/avastfilter.1 /usr/share/doc/avast4mail-VERSION/AUTHORS /usr/share/doc/avast4mail-VERSION/ChangeLog /usr/share/doc/avast4mail-VERSION/EULA /usr/share/doc/avast4mail-VERSION/FAQ /usr/share/doc/avast4mail-VERSION/INSTALL /usr/share/doc/avast4mail-VERSION/LICENSE /usr/share/doc/avast4mail-VERSION/NEWS /usr/share/doc/avast4mail-VERSION/README /var/lib/avastmail/notification /var/lib/avastmail/notification/recipient_body.tmpl /var/lib/avastmail/tmp /var/run/avastmail INTEGRATION INTO MTAs (Postfix, qmail, Sendmail, Exim): ======================================================= Setting Postfix MTA: -------------------- It's assumed you have already Postfix installed. In order to configure Postfix with avastfilter, you have to edit main Prostfix configuration file (/etc/postfix/master.cf). Please, before performing any changes in the Postfix configuration file, make a backup copy of the original configuration file. Now, please edit the configuration file and setup content filter: # ========================================================================== # service type private unpriv chroot wakeup maxproc command + args # (yes) (yes) (yes) (never) (100) # ========================================================================== smtp inet ...other stuff here, do not change... smtpd -o content_filter=filter:dummy filter unix - n n - 10 pipe flags=R user=avmail argv=/usr/bin/avastfilter -c /etc/mail/avastfilter.conf -f ${sender} ${recipient} localhost:10025 inet n - n - - smtpd -o content_filter= Postfix will run up to 10 content filters in parallel according the configuration. Instead of used limit, use whatever process limit is feasible for your machine. Now you must instruct avastfilter to send the message to the second instance of Postfix. Please edit /etc/mail/avastfilter.conf file and set MTIFACE option to do so. Here's an example of options of avastfilter's configuration file: AVIFACE="unix:/var/run/avastmail/mailscanner.sock" MTIFACE="inet:10025@localhost" TMPDIR="/var/lib/avastmail/tmp" HELONAME="localhost" and disable these options in the same file (by adding '#' in the begin of each line): #CHROOTDIR="/var" #USER="avmail" #GROUP="avmail" Secure your server by running your favorite firewall (e.q. iptables) to allow your server to be reached from outside only on port 25/tcp and not the other port (10025/tcp). Please, go to 'SETTING AVAST! DAEMON' section to setup avast! daemon. Setting Qmail MTA: ------------------ avastfilter will recieve a message instead of qmail-queue, then the message will be checked. If it's clean, the filter will transmit it forward to qmail-queue. Please, first patch qmail with 'qmailqueue-patch' to enable QMAILQUEUE environment variable. The patch is available at http://www.qmail.org. Then install patched qmail. Edit qmail statup script (e.g. /var/qmail/supervise/qmail-smtpd/run or /etc/rc.d/init.d/qmail or /etc/inetd.conf) and set QMAILQUEUE=/usr/bin/avastfilter variable by adding this line at the beginning of the file to call avastfilter instead of the original qmail-queue binary: QMAILQUEUE=/usr/bin/avastfilter export QMAILQUEUE Now set these options in /etc/mail/avastfilter.conf configuration file: AVIFACE="unix:/var/run/avastmail/mailscanner.sock" MTIFACE="file:/var/qmail/bin/qmail-queue" TMPDIR="/var/lib/avastmail/tmp" and disable these options in the same file (by adding '#' in the begin of each line): #CHROOTDIR="/var" #USER="avmail" #GROUP="avmail" Other options in /etc/mail/avastfilter.conf file can be modifyed by our own. Please, go to 'SETTING AVAST! DAEMON' section to setup avast! daemon. Setting Sendmail MTA: --------------------- NOTE: we recommed to use solution based on the libmilter facility of Sendmail (Sendmail 8.11 and higher). Please download and install avast4milter package instead. avastfilter is integrated into Sendmail by masquerading as the local delivery agent. This is done by editing /etc/mail/sendmail.cf file and modifying section called 'Local and Program Mailer specification' at the parameter 'P' of MLocal option (the parameter 'P' represents full path to the MDA used). There's also the parameter 'A' located at the same sentence of Sendmail configuration file and containing switches of the original MDA. None of these switches may be changed when modifying the original MDA path. Please, before performing any changes in the Sendmail configuration file, make a backup copy of the original configuration file. The appropriate modifyed option of the Sendmail configuration file can look like this: Mlocal, P=/usr/bin/avastfilter, F=lsDFMAw5:/|@qSPfhn9, S=EnvFromL/HdrFromL, R=EnvToL/HdrToL, T=DNS/RFC822/X-Unix, A=avastfilter -Y -a $h -d $u Now you must instruct avastfilter to send the message to the original MDA. In order to do so, you must insert the original MDA path to parameter MTIFACE in /etc/mail/avastfilter.conf configuration file (the path can be found in the Sendmail configuration back-up file). Here's an example of cooperation with procmail: AVIFACE="unix:/var/run/avastmail/mailscanner.sock" MTIFACE="file:/usr/bin/procmail" TMPDIR="/var/lib/avastmail/tmp" USER="avmail" GROUP="avmail" and disable this option in the same file (by adding '#' in the begin of each line): #CHROOTDIR="/var" Please, go to 'SETTING AVAST! DAEMON' section to setup avast! daemon. Setting Exim MTA version 4: --------------------------- It's assumed you have already Exim installed. Exim stores its configuration in the file /etc/exim4/exim4.conf or /etc/exim/exim.conf. If you look at the file, it's devided into MAIN, ROUTERS and TRANSPORTS sections. We will modify these sections to instruct the MTA to pipe messages through avastfilter and then filter messages intended to be discarded by /etc/exim/avastfilter script. Please, before performing any changes in the Exim configuration file, make a backup copy of the original configuration file. Now edit Exim's configuration file and insert: in 'MAIN CONFIGURATION SETTINGS' section: trusted_users = avmail trusted_groups = avmail system_filter = /etc/exim/avastfilter in 'ROUTERS CONFIGURATION' section after 'userforward' router: avast_router: driver = accept domains = +local_domains condition = "${if eq {$received_protocol}{avast-scanned} {0}{1}}" transport = avast_viruscheck in 'TRANSPORTS CONFIGURATION' section: avast_viruscheck: driver = pipe command = /usr/sbin/exim -oMr avast-scanned -bS use_bsmtp = true transport_filter = /usr/bin/avastfilter -f ${sender_address} ${pipe_addresses} user = avmail group = avmail log_output = true return_fail_output = true Create /etc/exim/avastfilter file with this content: # avast! mail filter if ($received_protocol is "avast-scanned" and $body_linecount is 0 and $message_headers does not contain "X-Antivirus-Status:") then seen finish endif Then edit /etc/mail/avastfilter.conf configuration file and setup these options: AVIFACE="local:/var/run/avastmail/mailscanner.sock" MTIFACE="" TMPDIR="/var/lib/avastmail/tmp" and disable these options: #CHROOTDIR=/var #USER="avmail" #GROUP="avmail" You can also enable notifying message sender about an infected mail by setting these options: DISCARD_INFECTED="yes" NOTIFY_RECIPIENT="yes" NOTIFY_RECIPIENT_TEMPLATE="/var/lib/avastmail/notification/recipient_body.tmpl" Please, go to 'SETTING AVAST! DAEMON' section to setup avast! daemon. INTEGRATION INTO MDAs (maildrop, procmail): =========================================== maildrop: --------- Maildrop is the mail filter/mail delivery agent that reads a mail message from standard input and then delivers the message to your mailbox. It's assumed you have already maildrop installed. maildrop optionally reads instruction from global /etc/maildroprc and local ~/.mailfilter files. Please insert your own filtering rules into one or both these files. Here's small example of local `~/.mailfilter' file enabling scanning mails and redirecting infected messages into Quarantine mailbox: exception { # scan message by avast! antivirus xfilter "/usr/bin/avastfilter" } if ( /^X-Antivirus-Status: Infected by .*/ ) { to "$HOME/Quarantine" } Please look at README file (MARKING OF SCANNED MESSAGES section) to see all possible message headers that can be inserted into scanned mail message by avastfilter. The section will help you to create your own filtering roules. Finally edit /etc/mail/avastfilter.conf configuration file and set these options: AVIFACE="unix:/var/run/avastmail/mailscanner.sock" MTIFACE="" TMPDIR="/var/lib/avastmail/tmp" CHROOTDIR="/var" USER="avmail" GROUP="avmail" RELAY_UNSCANNED="yes" RELAY_SCANERROR="yes" RELAY_ENCRYPTED="yes" RELAY_INFECTED="yes" NOTIFY_RECIPIENT="no" or if you want to send the notification message to the recipient: RELAY_INFECTED="no" DISCARD_INFECTED="yes" NOTIFY_RECIPIENT="yes" Please, go to 'SETTING AVAST! DAEMON' section to setup avast! daemon. procmail: --------- Procmail is a program for filtering, sorting and delivering electronic mail. It's assumed you have already procmail installed. Procmail optionally reads instruction from /etc/procmailrc and ~/.procmailrc files. Please insert your own filtering rules into one or both these files. Here's small example of local `~/.procmailrc' file enabling scanning mails and redirecting infected messages into Quarantine mailbox: :0fw | /usr/bin/avastfilter :0: * ^X-Antivirus-Status: Infected by .* $HOME/Quarantine Please look at the README file (MARKING OF SCANNED MESSAGES section) to see all possible message headers that can be inserted into scanned mail message by avastfilter. The section will help you to create your own filtering roules. Finally edit /etc/mail/avastfilter.conf configuration file and set these options: AVIFACE="unix:/var/run/avastmail/mailscanner.sock" MTIFACE="" TMPDIR="/var/lib/avastmail/tmp" CHROOTDIR="/var" USER="avmail" GROUP="avmail" RELAY_UNSCANNED="yes" RELAY_SCANERROR="yes" RELAY_ENCRYPTED="yes" RELAY_INFECTED="yes" NOTIFY_RECIPIENT="no" or if you want to send the notification message to the recipient: RELAY_INFECTED="no" DISCARD_INFECTED="yes" NOTIFY_RECIPIENT="yes" Please, go to 'SETTING AVAST! DAEMON' section to setup avast! daemon. INTEGRATION INTO MAIL RETRIEVERS (getmail): =========================================== getmail: -------- getmail is a mail retriever designed to allow you to get mails from one or more mail accounts on various mail servers using POP3/IMAP4 protocol. It's assumed you have already maildrop installed. getmail optionally reads instruction from local ~/.getmail/getmailrc files. Please insert this filtering rule into this file: [filter] type = Filter_external path = /usr/bin/avastfilter Finally edit /etc/mail/avastfilter.conf configuration file and set these options: AVIFACE="unix:/var/run/avastmail/mailscanner.sock" MTIFACE="" TMPDIR="/var/lib/avastmail/tmp" RELAY_UNSCANNED="yes" RELAY_SCANERROR="yes" RELAY_ENCRYPTED="yes" RELAY_INFECTED="yes" NOTIFY_RECIPIENT="no" and disable these options: #CHROOTDIR="/var" #USER="avmail" #GROUP="avmail" NOTE: avastfilter relays infected messages in this configuration! So you must insert a content filtering rule which will discard infected messages in your MDA. Without this rule local users will receive infected messages! Please, look at 'procmail' or 'dropmail' section to see how the rule looks like. Please, go to 'SETTING AVAST! DAEMON' section to setup avast! daemon. SETTING AVAST! DAEMON: ====================== Once the avast4mail package is installed, you'll also need avast! daemon 'avastd' running in the background and scanning files for avastfilter. To configure it for avastfilter, please create a new avastd scanner section in /etc/avastd.conf configuration file designed for mail scanning (see avastd.conf(5) manual page): [mail] daemoncount = 3 listen = /var/run/avastmail/mailscanner.sock user = avmail group = avmail rootdir = /var datadir = /var/lib/avast4 tempdir = /var/lib/avastmail/tmp licensefile = /var/lib/avast4/License.dat workdir = /var/lib/avastmail/tmp subdirs = false archivetype = A summaryarchive = false .... ***NOTE***: to enable avastd daemon working, you need a valid license file. libavastengine and avast4server packages does not contain anyone. To request a DEMO license, please visit the following web page: http://www.avast.com/linux-unix-trial-license-request.php FINAL STEPS: ============ (Re)start avastd and your MTA. Make sure avastd starts before the MTA and the avast! engine (libavastengine) is looking for a fresh virus database. We also suggest to activate avastd and MTA services at system startup. avast4mail-3.2.1-i586/NEWS0000644000000000000000000000076611401233054014712 0ustar rootroot00000000000000avast4mail NEWS: ================ 3.2.0 (2010-03-01) * updated documentation * supported /opt/avast4 installation directory * handling of user interrupts * fixed getting exit code of spawned applications 3.1.0 (2007-10-10) * message filtering and notifying rewritten from scratch * other X-Antivirus-Status message headers * new option to enable relaying of unscanned messages * created avastfilter.conf manual page * recipient_body.tmpl file contains notification message body * created DEB package avast4mail-3.2.1-i586/README0000644000000000000000000001666411401233054015077 0ustar rootroot00000000000000avast! Mail Filter Version 3.2.1 Tuesday, 1 Jun 2010 Copyright (C) 2005-2010, ALWIL Software Written by Frantisek Mensik OVERVIEW ======== This package contains avast! mail filter that allows you to enhance your local mail delivery system with avast! Antivirus. The filter is a utility for UNIX(-like) systems enabling protection against suspicious data in e-mail traffic. Each message processed by the filter is accepted or denied according to the scanner result. Infected message is deleted by default, bounced back to sender or relayed through the filter (the message is marked to be filtered by other programs). The program also allows you to send a notification to message recipient when an infection is found. Currently Posfix, qmail, Sendmail, Exim, maildrop and procmail are supported. Here's a short description, how avastmail works. The MTA server injects the message into avastfilter. Than the message is scanned by avastd daemon. And finally the message is injected back into the MTA. MTA ---> avastfilter(1) ---> MTA |^ v| avastd(8) For more informations about avast!, Postfix, Sendmail, qmail, Exim or procmail, please see websites: http://www.avast.com http://www.postfix.org http://www.qmail.org http://www.sendmail.org http://www.exim.org http://www.procmail.org The latest version of avast4mail can be found on this site: http://www.avast.com/eng/avast-for-linux-server.html NOTE: This package requires installed avast4server package! Recognizing viruses is based on the virus database currently loaded and used by avast! daemon! For installation and postinstallation instructions please refer to the INSTALL document and read the FAQ file. Futher information can be found in avastfilter(1) manual page. CONFIGURATION ============= Please, look at INSTALL file for the setting and configuration. You can find instructions how to integrate avast4mail into mail transmition agents (qmail, Postfix, Sendmail, Exim) or local delivery agents (procmail, maildrop) there. There is description how to setup avast! daemon to cooperate with avastfilter as well. avastfilter is documented in the following manual manpage: avastfilter(1) running the avastfilter command-line arguments: -c - specify alternative config file -f - message sender -d - message recipient(s) -h - print help stuff and exit -v - print version string and exit exit codes of avastfilter are as follows: * O Ok * >1 an error occure (see /usr/include/sysexits.h file) MARKING OF SCANNED MESSAGES =========================== avastfilter scans every e-mail message and marks it as Infected, Clean or specify an error occured during scanning. Every message scanned by avastfilter has this header: X-Antivirus: avast! (VPS ????-?, DD.MM.YYYY) avastfilter then appends result of the scanner to the message header: message is clean: X-Antivirus-Status: Clean message is encrypted: X-Antivirus-Status: Encrypted message is infected: X-Antivirus-Status: Infected by VIRUS_NAME message wasn't scanned: X-Antivirus-Status: Not scanned scanner not available: X-Antivirus-Status: Unscanned, scanner not available scanner error: X-Antivirus-Status: Unscanned, scan failed invalid scanner response: X-Antivirus-Status: Unscanned, invalid scanner response scan was stopped: X-Antivirus-Status: Unscanned, scan was stopped scanner isn't accessible: X-Antivirus-Status: Unscanned, scanner not working scan was timeouted: X-Antivirus-Status: Unscanned, scan was timeouted failed to scan: X-Antivirus-Status: Unscanned, scanner failed If the scanner finds an infection, avastfilter lists all infected attached files under 'X-Antivirus-Status: Infected by VIRUS_NAME' header in this form: Attachement: /ATTACHED/FILE/NAME.EXT Virus: VIRUS_NAME NOTE: if any of headers created by avastfilter already exists in the message, it's removed. This is to avoid your sorting rules being fooled by bogus headers. COOPERATION WITH PROCMAIL ========================= If you only set avastfilter to add its own message headers into every mail before forwarding, the message should be parsed by procmail for a string that shows the mail is infected (X-Antivirus-Status: Infected by VIRUS_NAME). To enable this, you must add additional rules to procmail configuration file to sort or discard detected viruses. Here is a small example of a procmail rule to move infected message to mailbox called infected: :0: * ^X-Antivirus-Status: Infected by .* infected If you change 'infected' mailbox to /dev/null, all infected mails will be discarded (NOTE: there's no way to retrive deleted mail). LOGGING AND SENDING NOTIFICATIONS ================================= avastfilter is able to log using syslog syslogd under the 'mail' facility (usualy into /var/log/mail.log file) or into a file or simply write error messages into error output (STDERR). avastfilter suports sending a notification message only to original message recipient(s) when a virus is found. Sending of notify messages must be enabled in the configuration file and path to message template file must be specified there too. Template files accept special keywords that can be expanded into the actual values. The following keywords are expanded: $SENDER$ - infected message sender's address $INFECTEDATTACHMENT$ - name of the the infected attachment $VIRUSNAME$ - name of the virus in the message $VPS$ - the virus database version used by avast! Antivirus NOTE: Nearly all modern viruses use forged message header so we suggest not to bounce infected message back and not to annoy (in most cases) innocent sender by a warning message. BUG REPORTS =========== If you find a bug or think you find a bug, it is very important to report it. If we don't know that the program is broken (or might be broken), we can't fix it. The steps: ---------- 1) Please ensure, if you use the latest program version. If your version is old, update it and then try to reproduce the bug. 2) Check to see if your bug has been reported yet. Go to the forum list http://forum.avast.com (avast! 4 for Linux/Unix section) to see if something that looks like your bug has been reported yet. 3) Attempt to reproduce the problem. Look into the program log file to see, what had happened when the bug occured, and then try to do what you were doing when it happened and see if you can do it again. 4) Report the bug to the developers. You can use the forum list for this purpose or write an email directly to the authors. Please, tell the developers everything about your system, your version of MTA, avast4mail and avast! Antivirus (avastd daemon and VPS file). Then add the bug description and instructions how to reproduce the problem (if it's possible). If someone has already reported a bug like yours, read the bug report carefully and make sure all information about the bug is in there. If anything differ or you had some additional experience with the bug, please add a comment with your information. If you've reported a bug and later get more information, please add a comment to your original bug report with that information. SUGGESTIONS =========== If you have a suggestion for avast4mail project, please report it to the authors.
