| | | #GENERAL NOTES: |
| | | # This file is a normal Perl code, interpreted by Perl itself. |
| | | # - make sure this file (or directory where it resides) is NOT WRITABLE |
| | | # by mere mortals (not even vscan/amavis; best to make it owned by root), |
| | | # otherwise it represents a severe security risk! |
| | | # - for values which are interpreted as booleans, it is recommended |
| | | # to use 1 for true, undef for false. |
| | | # THIS IS DIFFERENT FROM OLD AMAVIS VERSIONS where "no" also meant false, |
| | | # now it means true, like any nonempty string does! |
| | | # - Perl syntax applies. Most notably: strings in "" may include variables |
| | | # (which start with $ or @); to include characters @ and $ in double |
| | | # quoted strings, precede them by a backslash; in single-quoted strings |
| | | # the $ and @ lose their special meaning, so it is usually easier to use |
| | | # single quoted strings (or qw operator) for e-mail addresses. |
| | | # Still, in both cases a backslash needs to be doubled. |
| | | # - variables with names starting with a '@' are lists, the values assigned |
| | | # to them should be lists as well, e.g. ('one@foo', $mydomain, "three"); |
| | | # note the comma-separation and parenthesis. If strings in the list |
| | | # do not contain spaces nor variables, a Perl operator qw() may be used |
| | | # as a shorthand to split its argument on whitespace and produce a list |
| | | # of strings, e.g. qw( one@foo example.com three ); Note that the argument |
| | | # to qw is quoted implicitly and no variable interpretation is done within |
| | | # (no '$' variable evaluations). The #-initiated comments can NOT be used |
| | | # within a string. In other words, $ and # lose their special meaning |
| | | # within a qw argument, just like within '...' strings. |
| | | # - all e-mail addresses in this file and as used internally by the daemon |
| | | # are in their raw (rfc2821-unquoted and non-bracketed) form, i.e. |
| | | # Bob "Funny" Dude@example.com, not: "Bob \"Funny\" Dude"@example.com |
| | | # and not <"Bob \"Funny\" Dude"@example.com>; also: '' and not '<>'. |
| | | # - the term 'default value' in examples below refers to the value of a |
| | | # variable pre-assigned to it by the program; any explicit assignment |
| | | # to a variable in this configuration file overrides the default value; |
| | | |
| | | |
| | | # |
| | | # Section I - Essential daemon and MTA settings |
| | | # |
| | | |
| | | # $MYHOME serves as a quick default for some other configuration settings. |
| | | # More refined control is available with each individual setting further down. |
| | | # $MYHOME is not used directly by the program. No trailing slash! |
| | | $MYHOME = '/var/lib/amavis'; # (default is '/var/amavis') |
| | | |
| | | # $mydomain serves as a quick default for some other configuration settings. |
| | | # More refined control is available with each individual setting further down. |
| | | # $mydomain is never used directly by the program. |
| | | $mydomain = 'example.com'; # (no useful default) |
| | | |
| | | # $myhostname = 'host.example.com'; # fqdn of this host, default by uname(3) |
| | | |
| | | # Set the user and group to which the daemon will change if started as root |
| | | # (otherwise just keeps the UID unchanged, and these settings have no effect): |
| | | $daemon_user = 'amavis'; # (no default (undef)) |
| | | $daemon_group = 'amavis'; # (no default (undef)) |
| | | |
| | | # Runtime working directory (cwd), and a place where |
| | | # temporary directories for unpacking mail are created. |
| | | # if you change this, you might want to modify the cleanup() |
| | | # function in /etc/init.d/amavisd-new |
| | | # (no trailing slash, may be a scratch file system) |
| | | $TEMPBASE = $MYHOME; # (must be set if other config vars use is) |
| | | #$TEMPBASE = "$MYHOME/tmp"; # prefer to keep home dir /var/amavis clean? |
| | | |
| | | # $helpers_home sets environment variable HOME, and is passed as option |
| | | # 'home_dir_for_helpers' to Mail::SpamAssassin::new. It should be a directory |
| | | # on a normal persistent file system, not a scratch or temporary file system |
| | | #$helpers_home = $MYHOME; # (defaults to $MYHOME) |
| | | |
| | | # Run the daemon in the specified chroot jail if nonempty: |
| | | #$daemon_chroot_dir = $MYHOME; # (default is undef, meaning: do not chroot) |
| | | |
| | | $pid_file = "/var/run/amavis/amavisd.pid"; # (default: "$MYHOME/amavisd.pid") |
| | | $lock_file = "/var/run/amavis/amavisd.lock"; # (default: "$MYHOME/amavisd.lock") |
| | | |
| | | # set environment variables if you want (no defaults): |
| | | $ENV{TMPDIR} = $TEMPBASE; # wise to set TMPDIR, but not obligatory |
| | | #... |
| | | |
| | | |
| | | # MTA SETTINGS, UNCOMMENT AS APPROPRIATE, |
| | | # both $forward_method and $notify_method default to 'smtp:127.0.0.1:10025' |
| | | |
| | | # POSTFIX, or SENDMAIL in dual-MTA setup, or EXIM V4 |
| | | # (set host and port number as required; host can be specified |
| | | # as IP address or DNS name (A or CNAME, but MX is ignored) |
| | | $forward_method = 'smtp:127.0.0.1:10025'; # where to forward checked mail |
| | | $notify_method = $forward_method; # where to submit notifications |
| | | |
| | | # NOTE: The defaults (above) are good for Postfix or dual-sendmail. You MUST |
| | | # uncomment the appropriate settings below if using other setups! |
| | | |
| | | # SENDMAIL MILTER, using amavis-milter.c helper program: |
| | | # SEE amavisd-new-milter package docs FOR DEBIAN INSTRUCTIONS |
| | | #$forward_method = undef; # no explicit forwarding, sendmail does it by itself |
| | | # milter; option -odd is needed to avoid deadlocks |
| | | #$notify_method = 'pipe:flags=q argv=/usr/sbin/sendmail -Ac -i -odd -f ${sender} -- ${recipient}'; |
| | | # just a thought: can we use use -Am instead of -odd ? |
| | | |
| | | # SENDMAIL (old non-milter setup, as relay): |
| | | #$forward_method = 'pipe:flags=q argv=/usr/sbin/sendmail -C/etc/sendmail.orig.cf -i -f ${sender} -- ${recipient}'; |
| | | #$notify_method = $forward_method; |
| | | |
| | | # SENDMAIL (old non-milter setup, amavis.c calls local delivery agent): |
| | | #$forward_method = undef; # no explicit forwarding, amavis.c will call LDA |
| | | #$notify_method = 'pipe:flags=q argv=/usr/sbin/sendmail -Ac -i -f ${sender} -- ${recipient}'; |
| | | |
| | | # EXIM v3 (not recommended with v4 or later, which can use SMTP setup instead): |
| | | #$forward_method = 'pipe:flags=q argv=/usr/sbin/exim -oMr scanned-ok -i -f ${sender} -- ${recipient}'; |
| | | #$notify_method = $forward_method; |

| | | #$forward_method = "bsmtp:$MYHOME/out-%i-%n.bsmtp"; |
| | | #$notify_method = $forward_method; |
| | | |
| | | |
| | | # Net::Server pre-forking settings |
| | | # You may want $max_servers to match the width of your MTA pipe |
| | | # feeding amavisd, e.g. with Postfix the 'Max procs' field in the |
| | | # master.cf file, like the '2' in the: smtp-amavis unix - - n - 2 smtp |
| | | # |
| | | $max_servers = 2; # number of pre-forked children (default 2) |
| | | $max_requests = 10; # retire a child after that many accepts (default 10) |
| | | |
| | | $child_timeout=5*60; # abort child if it does not complete each task in n sec |
| | | # (default: 8*60 seconds) |
| | | |
| | | # Check also the settings of @av_scanners at the end if you want to use |
| | | # virus scanners. If not, you may want to delete the whole long assignment |
| | | # to the variable @av_scanners, which will also remove the virus checking |
| | | # code (e.g. if you only want to do spam scanning). |
| | | |
| | | # Here is a QUICK WAY to completely DISABLE some sections of code |
| | | # that WE DO NOT WANT (it won't even be compiled-in). |
| | | # For more refined controls leave the following two lines commented out, |
| | | # and see further down what these two lookup lists really mean. |
| | | # |
| | | # @bypass_virus_checks_acl = qw( . ); # uncomment to DISABLE anti-virus code |
| | | # @bypass_spam_checks_acl = qw( . ); # uncomment to DISABLE anti-spam code |
| | | # |
| | | # Any setting can be changed with a new assignment, so make sure |
| | | # you do not unintentionally override these settings further down! |
| | | @bypass_spam_checks_acl = qw( . ); # No default dependency on spamassassin |
| | | |
| | | # Lookup list of local domains (see README.lookups for syntax details) |
| | | # |
| | | # NOTE: |
| | | # For backwards compatibility the variable names @local_domains (old) and |
| | | # @local_domains_acl (new) are synonyms. For consistency with other lookups |
| | | # the name @local_domains_acl is now preferred. It also makes it more |
| | | # obviously distinct from the new %local_domains hash lookup table. |
| | | # |
| | | # local_domains* lookup tables are used in deciding whether a recipient |
| | | # is local or not, or in other words, if the message is outgoing or not. |
| | | # This affects inserting spam-related headers for local recipients, |
| | | # limiting recipient virus notifications (if enabled) to local recipients, |
| | | # in deciding if address extension may be appended, and in SQL lookups |
| | | # for non-fqdn addresses. Set it up correctly if you need features |
| | | # that rely on this setting (or just leave empty otherwise). |
| | | # |
| | | # With Postfix (2.0) a quick reminder on what local domains normally are: |
| | | # a union of domains specified in: $mydestination, $virtual_alias_domains, |
| | | # $virtual_mailbox_domains, and $relay_domains. |
| | | # |
| | | @local_domains_acl = ( ".$mydomain" ); # $mydomain and its subdomains |
| | | # @local_domains_acl = ( ".$mydomain", "my.other.domain" ); |
| | | # @local_domains_acl = qw(); # default is empty, no recipient treated as local |
| | | # @local_domains_acl = qw( .example.com ); |
| | | # @local_domains_acl = qw( .example.com !host.sub.example.net .sub.example.net ); |
| | | |
| | | # or alternatively(A), using a Perl hash lookup table, which may be assigned |
| | | # directly, or read from a file, one domain per line; comments and empty lines |
| | | # are ignored, a dot before a domain name implies its subdomains: |
| | | # |
| | | #read_hash(\%local_domains, '/etc/amavis/local_domains'); |
| | | |
| | | #or alternatively(B), using a list of regular expressions: |
| | | # $local_domains_re = new_RE( qr'[@.]example\.com$'i ); |
| | | # |
| | | # see README.lookups for syntax and semantics |

| | | # Section II - MTA specific (defaults should be ok) |
| | | # |
| | | |
| | | # if $relayhost_is_client is true, the IP address in $notify_method and |
| | | # $forward_method is dynamically overridden with SMTP client peer address |
| | | # (if available), which makes it possible for several hosts to share one |
| | | # daemon. The static port number is also overridden, and is dynamically |
| | | # calculated as being one above the incoming SMTP/LMTP session port number. |
| | | # |
| | | # These are logged at level 3, so enable logging until you know you got it |
| | | # right. |

| | | |
| | | $insert_received_line = 1; # behave like MTA: insert 'Received:' header |
| | | # (does not apply to sendmail/milter) |
| | | # (default is true (1) ) |
| | | |
| | | # AMAVIS-CLIENT PROTOCOL INPUT SETTINGS (e.g. with sendmail milter) |
| | | # (used with amavis helper clients like amavis-milter.c and amavis.c, |
| | | # NOT needed for Postfix and Exim or dual-sendmail - keep it undefined.) |
| | | #$unix_socketname = "/var/lib/amavis/amavisd.sock"; # amavis helper protocol socket |
| | | $unix_socketname = undef; # disable listening on a unix socket |
| | | # (default is undef, i.e. disabled) |
| | | |
| | | # Do we receive quoted or raw addresses from the helper program? |
| | | # (does not apply to SMTP; defaults to true) |
| | | #$gets_addr_in_quoted_form = 1; # "Bob \"Funny\" Dude"@example.com |
| | | #$gets_addr_in_quoted_form = 0; # Bob "Funny" Dude@example.com |
| | | |
| | | |
| | | |
| | | # SMTP SERVER (INPUT) PROTOCOL SETTINGS (e.g. with Postfix, Exim v4, ...) |
| | | # (used when MTA is configured to pass mail to amavisd via SMTP or LMTP) |
| | | $inet_socket_port = 10024; # accept SMTP on this local TCP port |
| | | # (default is undef, i.e. disabled) |
| | | # multiple ports may be provided: $inet_socket_port = [10024, 10026, 10028]; |
| | | |
| | | # SMTP SERVER (INPUT) access control |
| | | # - do not allow free access to the amavisd SMTP port !!! |
| | | # |
| | | # when MTA is at the same host, use the following (one or the other or both): |
| | | $inet_socket_bind = '127.0.0.1'; # limit socket bind to loopback interface |
| | | # (default is '127.0.0.1') |
| | | @inet_acl = qw( 127.0.0.1 ); # allow SMTP access only from localhost IP |
| | | # (default is qw( 127.0.0.1 ) ) |
| | | |
| | | # when MTA (one or more) is on a different host, use the following: |
| | | # @inet_acl = qw(127/8 10.1.0.1 10.1.0.2); # adjust the list as appropriate |
| | | # $inet_socket_bind = undef; # bind to all IP interfaces if undef |
| | | # |
| | | # Example1: |
| | | # @inet_acl = qw( 127/8 10/8 172.16/12 192.168/16 ); |
| | | # permit only SMTP access from loopback and rfc1918 private address space |
| | | # |
| | | # Example2: |
| | | # @inet_acl = qw( !192.168.1.12 172.16.3.3 !172.16.3/255.255.255.0 |
| | | # 127.0.0.1 10/8 172.16/12 192.168/16 ); |
| | | # matches loopback and rfc1918 private address space except host 192.168.1.12 |
| | | # and net 172.16.3/24 (but host 172.16.3.3 within 172.16.3/24 still matches) |
| | | # |
| | | # Example3: |
| | | # @inet_acl = qw( 127/8 |
| | | # !172.16.3.0 !172.16.3.127 172.16.3.0/25 |
| | | # !172.16.3.128 !172.16.3.255 172.16.3.128/25 ); |
| | | # matches loopback and both halves of the 172.16.3/24 C-class, |
| | | # split into two subnets, except all four broadcast addresses |
| | | # for these subnets |
| | | # |
| | | # See README.lookups for details on specifying access control lists. |

| | | # Section III - Logging |
| | | # |
| | | |
| | | # true (e.g. 1) => syslog; false (e.g. 0) => logging to file |

| | | |

| | | #$hdr_encoding = 'iso-8859-1'; # (default: 'iso-8859-1') |
| | | # |
| | | # to be used in notification body text: its encoding and Content-type.charset |

| | | |
| | | # Default template texts for notifications may be overruled by directly |

| | | # Here is an overall picture (sequence of events) of how pieces fit together |
| | | # (only virus controls are shown, spam controls work the same way): |
| | | # |
| | | # bypass_virus_checks? ==> PASS |
| | | # no viruses? ==> PASS |
| | | # log virus if $log_templ is nonempty |
| | | # quarantine if $virus_quarantine_to is nonempty |
| | | # notify admin if $virus_admin (lookup) nonempty |
| | | # notify recips if $warnvirusrecip and (recipient is local or $warn_offsite) |
| | | # add address extensions if adding extensions is enabled and virus will pass |
| | | # send (non-)delivery notifications |
| | | # to sender if DSN needed (BOUNCE or ($warn_virus_sender and D_PASS)) |
| | | # virus_lovers or final_destiny==D_PASS ==> PASS |
| | | # DISCARD (2xx) or REJECT (5xx) (depending on final_*_destiny) |
| | | # |
| | | # Equivalent flow diagram applies for spam checks. |
| | | # If a virus is detected, spam checking is skipped entirely. |
| | | |
| | | # The following symbolic constants can be used in *destiny settings: |
| | | # |
| | | # D_PASS mail will pass to recipients, regardless of bad contents; |
| | | # |
| | | # D_DISCARD mail will not be delivered to its recipients, sender will NOT be |
| | | # notified. Effectively we lose mail (but will be quarantined |
| | | # unless disabled). Losing mail is not decent for a mailer, |
| | | # but might be desired. |
| | | # |
| | | # D_BOUNCE mail will not be delivered to its recipients, a non-delivery |
| | | # notification (bounce) will be sent to the sender by amavisd-new; |
| | | # Exception: bounce (DSN) will not be sent if a virus name matches |
| | | # $viruses_that_fake_sender_re, or to messages from mailing lists |
| | | # (Precedence: bulk|list|junk); |
| | | # |
| | | # D_REJECT mail will not be delivered to its recipients, sender should |
| | | # preferably get a reject, e.g. SMTP permanent reject response |
| | | # (e.g. with milter), or non-delivery notification from MTA |
| | | # (e.g. Postfix). If this is not possible (e.g. different recipients |
| | | # have different tolerances to bad mail contents and not using LMTP) |
| | | # amavisd-new sends a bounce by itself (same as D_BOUNCE). |
| | | # |
| | | # Notes: |
| | | # D_REJECT and D_BOUNCE are similar, the difference is in who is responsible |
| | | # for informing the sender about non-delivery, and how informative |
| | | # the notification can be (amavisd-new knows more than MTA); |
| | | # With D_REJECT, MTA may reject original SMTP, or send DSN (delivery status |
| | | # notification, colloquially called 'bounce') - depending on MTA; |
| | | # Best suited for sendmail milter, especially for spam. |
| | | # With D_BOUNCE, amavisd-new (not MTA) sends DSN (can better explain the |
| | | # reason for mail non-delivery, but unable to reject the original |
| | | # SMTP session). Best suited to reporting viruses, and for Postfix |
| | | # and other dual-MTA setups, which can't reject original client SMTP |
| | | # session, as the mail has already been enqueued. |
| | | |
| | | $final_virus_destiny = D_DISCARD; # (defaults to D_BOUNCE) |
| | | $final_banned_destiny = D_BOUNCE; # (defaults to D_BOUNCE) |
| | | $final_spam_destiny = D_REJECT; # (defaults to D_REJECT) |
| | | $final_bad_header_destiny = D_PASS; # (defaults to D_PASS), D_BOUNCE suggested |
| | | |
| | | # Alternatives to consider for spam: |
| | | # - use D_PASS if clients will do filtering based on inserted mail headers; |
| | | # - use D_DISCARD, if kill_level is set safely high; |
| | | # - use D_BOUNCE instead of D_REJECT if not using milter; |
| | | # |
| | | # D_BOUNCE is preferred for viruses, but consider: |
| | | # - use D_DISCARD to avoid bothering the rest of the network, it is hopeless |
| | | # to try to keep up with the viruses that faker the envelope sender anyway, |
| | | # and bouncing only increases the network cost of viruses for everyone |
| | | # - use D_PASS (or virus_lovers) and $warnvirussender=1 to deliver viruses; |
| | | # - use D_REJECT instead of D_BOUNCE if using milter and under heavy |
| | | # virus storm; |
| | | # |
| | | # Don't bother to set both D_DISCARD and $warn*sender=1, it will get mapped |

| | | # or a ref to a hash lookup table, or a regexp lookup table object, |
| | | # which makes possible to set up per-recipient quarantine addresses. |
| | | # |
| | | # The value of scalar $virus_quarantine_to/$spam_quarantine_to (or a |
| | | # per-recipient lookup result from the hash table %$virus_quarantine_to) |
| | | # is/are interpreted as follows: |
| | | # |
| | | # VARIANT 1: |
| | | # empty or undef disables quarantine; |
| | | # |
| | | # VARIANT 2: |
| | | # a string NOT containing an '@'; |
| | | # amavisd will behave as a local delivery agent (LDA) and will quarantine |
| | | # viruses to local files according to hash %local_delivery_aliases (pseudo |
| | | # aliases map) - see subroutine mail_to_local_mailbox() for details. |
| | | # Some of the predefined aliases are 'virus-quarantine' and 'spam-quarantine'. |
| | | # Setting $virus_quarantine_to ($spam_quarantine_to) to this string will: |
| | | # |
| | | # * if $QUARANTINEDIR is a directory, each quarantined virus will go |
| | | # to a separate file in the $QUARANTINEDIR directory (traditional |
| | | # amavis style, similar to maildir mailbox format); |
| | | # |
| | | # * otherwise $QUARANTINEDIR is treated as a file name of a Unix-style |
| | | # mailbox. All quarantined messages will be appended to this file. |
| | | # Amavisd child process must obtain an exclusive lock on the file during |
| | | # delivery, so this may be less efficient than using individual files |
| | | # or forwarding to MTA, and it may not work across NFS or other non-local |
| | | # file systems (but may be handy for pickup of quarantined files via IMAP |
| | | # for example); |
| | | # |
| | | # VARIANT 3: |
| | | # any email address (must contain '@'). |
| | | # The e-mail messages to be quarantined will be handed to MTA |
| | | # for delivery to the specified address. If a recipient address local to MTA |
| | | # is desired, you may leave the domain part empty, e.g. 'infected@', but the |
| | | # '@' character must nevertheless be included to distinguish it from variant 2. |
| | | # |
| | | # This method enables more refined delivery control made available by MTA |
| | | # (e.g. its aliases file, other local delivery agents, dealing with |
| | | # privileges and file locking when delivering to user's mailbox, nonlocal |
| | | # delivery and forwarding, fan-out lists). Make sure the mail-to-be-quarantined |
| | | # will not be handed back to amavisd for checking, as this will cause a loop |
| | | # (hopefully broken at some stage)! If this can be assured, notifications |
| | | # will benefit too from not being unnecessarily virus-scanned. |
| | | # |
| | | # By default this is safe to do with Postfix and Exim v4 and dual-sendmail |

| | | # ENVELOPE SENDER WHITELISTING / BLACKLISTING - GLOBAL (RECIPIENT-INDEPENDENT) |
| | | # (affects spam checking only, has no effect on virus and other checks) |
| | | |
| | | # WHITELISTING: use ENVELOPE SENDER lookups to ENSURE DELIVERY from whitelisted |
| | | # senders even if the message would be recognized as spam. Effectively, for |
| | | # the specified senders, message recipients temporarily become 'spam_lovers'. |
| | | # To avoid surprises, whitelisted sender also suppresses inserting/editing |
| | | # the tag2-level header fields (X-Spam-*, Subject), appending spam address |
| | | # extension, and quarantining. |
| | | |
| | | # BLACKLISTING: messages from specified SENDERS are DECLARED SPAM. |
| | | # Effectively, for messages from blacklisted senders, spam level |
| | | # is artificially pushed high, and the normal spam processing applies, |
| | | # resulting in 'X-Spam-Flag: YES', high 'X-Spam-Level' bar and other usual |
| | | # reactions to spam, including possible rejection. If the message nevertheless |
| | | # still passes (e.g. for spam loving recipients), it is tagged as BLACKLISTED |
| | | # in the 'X-Spam-Status' header field, but the reported spam value and |
| | | # set of tests in this report header field (if available from SpamAssassin, |
| | | # which may have not been called) is not adjusted. |
| | | # |
| | | # A sender may be both white- and blacklisted at the same time, settings |
| | | # are independent. For example, being both white- and blacklisted, message |
| | | # is delivered to recipients, but is not tagged as spam (X-Spam-Flag: No; |
| | | # X-Spam-Status: No, ...), but the reported spam level (if computed) may |
| | | # still indicate high spam score. |
| | | # |
| | | # If ALL recipients of the message either white- or blacklist the sender, |
| | | # spam scanning (calling the SpamAssassin) is bypassed, saving on time. |
| | | # |
| | | # The following variables (lookup tables) are available, with the semantics |
| | | # and syntax as specified in README.lookups: |

| | | # Besides a simple string (full program path name or just the basename |

| | | # program names or full paths - the first match in the list will be used; |
| | | # As a special case for more complex scanners, this field may be |
| | | # a subroutine reference, and the whole n-tuple is passed to it as args. |
| | | # 3. command arguments to be given to the scanner program; |
| | | # a substring {} will be replaced by the directory name to be scanned, |
| | | # i.e. "$tempdir/parts", a "*" will be replaced by file names of parts; |
| | | # 4. an array ref of av scanner exit status values, or a regexp (to be |
| | | # matched against scanner output), indicating NO VIRUSES found; |
| | | # 5. an array ref of av scanner exit status values, or a regexp (to be |
| | | # matched against scanner output), indicating VIRUSES WERE FOUND; |
| | | # Note: the virus match prevails over a 'not found' match, so it is safe |
| | | # even if the no. 4. matches for viruses too; |
| | | # 6. a regexp (to be matched against scanner output), returning a list |
| | | # of virus names found. |
| | | # 7. and 8.: (optional) subroutines to be executed before and after scanner |
| | | # (e.g. to set environment or current directory); |
| | | # see examples for these at KasperskyLab AVP and Sophos sweep. |
| | | |
| | | # NOTES: |
| | | # |
| | | # - NOT DEFINING @av_scanners (e.g. setting it to empty list, or deleting the |
| | | # whole assignment) TURNS OFF LOADING AND COMPILING OF THE ANTIVIRUS CODE |
| | | # (which can be handy if all you want to do is spam scanning); |
| | | # |
| | | # - the order matters: although _all_ available entries from the list are |
| | | # always tried regardless of their verdict, scanners are run in the order |
| | | # specified: the report from the first one detecting a virus will be used |
| | | # (providing virus names and scanner output); REARRANGE THE ORDER TO WILL; |
| | | # |
| | | # - it doesn't hurt to keep an unused command line scanner entry in the list |
| | | # if the program can not be found; the path search is only performed once |
| | | # during the program startup; |
| | | # |
| | | # COROLLARY: to disable a scanner that _does_ exist on your system, |
| | | # comment out its entry or use undef or '' as its program name/path |
| | | # (second parameter). An example where this is almost a must: disable |
| | | # Sophos 'sweep' if you have its daemonized version Sophie or SAVI-Perl |
| | | # (same for Trophie/vscan, and clamd/clamscan), or if another unrelated |
| | | # program happens to have a name matching one of the entries ('sweep' |
| | | # again comes to mind); |
| | | # |
| | | # - it DOES HURT to keep unwanted entries which use INTERNAL SUBROUTINES |
| | | # for interfacing (where the second parameter starts with \&). |
| | | # Keeping such entry and not having a corresponding virus scanner daemon |
| | | # causes an unnecessary connection attempt (which eventually times out, |
| | | # but it wastes precious time). For this reason the daemonized entries |
| | | # are commented in the distribution - just remove the '#' where needed. |
