+
+#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, and 0 or undef or '' 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;  customary: vscan or amavis)
+$daemon_group = 'amavis';	# (no default;  customary: vscan or amavis)
+
+# Runtime working directory (cwd), and a place where
+# temporary directories for unpacking mail are created.
+# (no trailing slash, may be a scratch file system)
+#$TEMPBASE = $MYHOME;	        # (must be set if other config vars use is)
+$TEMPBASE = "$MYHOME/tmp";     # prefer to keep home dir /var/amavis clean?
+
+$db_home = "$MYHOME/db";	# DB databases directory, default "$MYHOME/db"
+
+# $helpers_home sets environment variable HOME, and is passed as option
+# 'home_dir_for_helpers' to Mail::SpamAssassin::new. It should be a directory
+# on a normal persistent file system, not a scratch or temporary file system
+$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  = "$MYHOME/amavisd.pid";  # (default is "$MYHOME/amavisd.pid")
+#$lock_file = "$MYHOME/amavisd.lock"; # (default is "$MYHOME/amavisd.lock")
+
+# set environment variables if you want (no defaults):
+$ENV{TMPDIR} = $TEMPBASE;       # wise to set TMPDIR, but not obligatory
+#...
+
+# MTA SETTINGS, UNCOMMENT AS APPROPRIATE,
+# both $forward_method and $notify_method default to 'smtp:[127.0.0.1]:10025'
+
+# POSTFIX, or SENDMAIL in dual-MTA setup, or EXIM V4
+# (set host and port number as required; host can be specified
+# as an IP address or a DNS name (A or CNAME, but MX is ignored)
+#$forward_method = 'smtp:[127.0.0.1]:10025';  # where to forward checked mail
+#$notify_method = $forward_method;            # where to submit notifications
+
+# To make it possible for several hosts to share one content checking daemon,
+# the IP address and/or the port number in $forward_method and $notify_method
+# may be spacified as an asterisk. An asterisk in the colon-separated
+# second field (host) will be replaced by the SMTP client peer address,
+# An asterisk in the third field (tcp port) will be replaced by the incoming
+# SMTP/LMTP session port number plus one. This obsoletes the previously used
+# less flexible configuration parameter $relayhost_is_client. An example:
+#   $forward_method = 'smtp:*:*'; $notify_method = 'smtp:*:10587';
+
+
+# NOTE: The defaults (above) are good for Postfix or dual-sendmail. You MUST
+#       uncomment the appropriate settings below if using other setups!
+
+# SENDMAIL MILTER, using amavis-milter.c helper program:
+#$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 = $forward_method;
+
+# prefer to collect mail for forwarding as BSMTP files?
+#$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  =  4;   # 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_maps = (1);  # uncomment to DISABLE anti-virus code
+# @bypass_spam_checks_maps  = (1);  # 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!
+
+
+# Lookup list of local domains (see README.lookups for syntax details)
+#
+# @local_domains_maps list of 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 $relay_domains.
+
+@local_domains_maps = ( [".$mydomain"] );  # $mydomain and its subdomains
+# @local_domains_maps = (); # default is empty list, no recip. considered local
+# @local_domains_maps =  # using ACL lookup table
+#   ( [ ".$mydomain", '.example.com', 'sub.example.net' ] );
+# @local_domains_maps =  # similar, split list elements on whitespace
+#   ( [qw( .example.com !host.sub.example.net .sub.example.net )] );
+# @local_domains_maps = ( new_RE( qr'[@.]example\.com$'i ) );   # using regexp

+# 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 set for all recipients? ==> 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 $warn_offsite)
+#   add address extensions for local recipients (when enabled)
+#   send (non-)delivery notifications
+#      to sender if DSN needed (BOUNCE or ($warnvirussender 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.
+
+########
+#
+# Please think about what you are doing when you set these options.
+# If necessary, question your origanization's e-mail policies:
+#
+# D_BOUNCE contributes to the overall spread of virii and spam on the
+# internet. Both the envelope and header from addresses can be forged
+# accurately with no effort.
+#
+# D_DISCARD breaks internet mail specifications. However, with a
+# properly implemented Quaratine system, the concern for breaking the
+# specification is addressed to some extent.
+#
+# D_PASS is the safest way to handle e-mails. You must implement
+# client-side filtering to handle this method.

+#   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

+# @virus_lovers_maps list of lookup tables:
+#   (this should be considered a policy option, is does not disable checks,
+#   see bypass*checks for that!)
+#
+# Exclude certain RECIPIENTS from virus filtering by adding their (lower-cased)
+# envelope e-mail address (or domain only) to one of the lookup tables in
+# the @virus_lovers_maps list - see README.lookups and examples.
+# Make sure the appropriate form (e.g. external/internal) of address
+# is used in case of virtual domains, or when mapping external to internal
+# addresses, etc. - this is MTA-specific.
+#
+# Notifications would still be generated however (see the overall
+# picture above), and infected mail (if passed) gets additional header:
+#   X-AMaViS-Alert: INFECTED, message contains virus: ...
+# (header not inserted with milter interface!)
+#
+# NOTE (milter interface only): in case of multiple recipients,
+# it is only possible to drop or accept the message in its entirety - for all
+# recipients. If all of them are virus lovers, we'll accept mail, but if
+# at least one recipient is not a virus lover, we'll discard the message.
+
+
+# @bypass_virus_checks_maps list of lookup tables:
+#   (this is mainly a time-saving option, unlike virus_lovers* !)
+#
+# Similar in concept to @virus_lovers_maps, a @bypass_virus_checks_maps
+# is used to skip entirely the decoding, unpacking and virus checking,
+# but only if ALL recipients match the lookup.
+#
+# @bypass_virus_checks_maps does NOT GUARANTEE the message will NOT be checked
+# for viruses - this may still happen when there is more than one recipient
+# for a message, and not all of them match these lookup tables. To guarantee
+# virus delivery, a recipient must also match @virus_lovers_maps lookups
+# (but see milter limitations above),
+
+# NOTE: it would not be clever to base virus checks on SENDER address,
+# since there are no guarantees that it is genuine. Many viruses
+# and spam messages fake sender address. To achieve selective filtering
+# based on the source of the mail (e.g. IP address, MTA port number, ...),
+# use mechanisms provided by MTA if available.
+
+
+# Similar to lists of lookup tables controlling virus checking, there are
+# counterparts for spam scanning, banned names/types, and headers_checks
+# control:
+#   @spam_lovers_maps,
+#   @banned_files_lovers_maps,
+#   @bad_header_lovers_maps
+# and:
+#   @bypass_spam_checks_maps,
+#   @bypass_banned_checks_maps,
+#   @bypass_header_checks_maps
+
+# Example:
+#   @bypass_header_checks_maps = ( [qw( user@example.com )] );
+#   @bad_header_lovers_maps    = ( [qw( user@example.com )] );
+
+# The following example disables spam checking altogether,
+# since it matches any recipient e-mail address (any address
+# is a subdomain of the top-level root DNS domain):
+#   @bypass_spam_checks_maps = (1);
+
+
+# See README.lookups for further detail, and examples below.
+
+# In the following example a list of lookup tables @virus_lovers_maps
+# contains three elements, the first is a reference to an ACL lookup
+# table (brackets in Perl indicate a ref to a list), the second is a
+# reference to a hash lookup table (braces in Perl indicate a ref to a hash),
+# the third is a regexp lookup table, indicated by the type of the object:
+#
+#@virus_lovers_maps = (
+# [ qw( me@lab.xxx.com !lab.xxx.com .xxx.com yyy.org ) ],
+# { "postmaster\@$mydomain" => 1, # double quotes permit variable evaluation
+#   'postmaster@example.com'=> 1, # in single quotes the '@' need not be quoted
+#   'abuse@example.com'=> 1,
+#   'some.user@'       => 1,  # this recipient, regardless of domain
+#   'boss@example.com' => 0,  # never, even if domain matches
+#   'example.com'      => 1,  # this domain, but not its subdomains
+#   '.example.com'     => 1,  # this domain, including its subdomains
+# },

+#);
+
+#@bad_header_lovers_maps = (
+# ["postmaster\@", "abuse\@$mydomain"],
+#);
+
+# to save some typing of quotes and commas, a Perl operator qw can be used
+# to split its argument on whitespace and to quote resulting elements:
+#@bypass_spam_checks_maps = (
+#  [ qw( some.ddd !butnot.example.com .example.com ) ],
+#);
+
+
+# don't run spam check for these RECIPIENT domains:
+#   @bypass_spam_checks_maps = ( [qw( d1.com .d2.com a.d3.com )] );
+# or the other way around (bypass check for all BUT these):
+#   @bypass_spam_checks_maps = ( [qw( !d1.com !.d2.com !a.d3.com . )] );
+# a practical application: don't check outgoing mail for spam:
+#   @bypass_spam_checks_maps = ( [ "!.$mydomain", "." ] );
+# (a downside of which is that such mail will not count as ham in SA bayes db)

+# No need to uncomment the following assignment if the default is ok.

+#     ' WHERE (users.policy_id=policy.id) AND (users.email IN (%k))'.
+#     ' ORDER BY users.priority DESC';
+#
+# The SQL select clause to check sender in per-recipient whitelist/blacklist
+# The first SELECT argument '?' will be users.id from recipient SQL lookup,
+# the %k will be sender addresses (e.g. full address, domain only, catchall).
+# The default value is:
+#   $sql_select_white_black_list = 'SELECT wb FROM wblist,mailaddr'.
+#     ' WHERE (wblist.rid=?) AND (wblist.sid=mailaddr.id)'.
+#     '   AND (mailaddr.email IN (%k))'.
+#     ' ORDER BY mailaddr.priority DESC';
+#
+# To disable SQL white/black list, set to undef (otherwise comment-out
+# the following statement, leaving it at the default value):
+$sql_select_white_black_list = undef;  # undef disables SQL white/blacklisting
+
+
+# If passing malware to certain recipients ($final_*_destiny=D_PASS or

+# This is sometimes known as the 'plus addressing'. Appending address

+# - recipient does not match lookup tables @local_domains_maps;
+# - lookup into corresponding @addr_extension_*_maps results
+#   in an empty string or undef;
+# - $recipient_delimiter is empty (see below)

+# ENVELOPE SENDER SOFT-WHITELISTING / SOFT-BLACKLISTING
+
+# Instead of strongly black- or whitelisting, a softer approach is to add

+# Positive points lean towards blacklisting, negative towards whitelisting.
+# This is much like adding SA rules or using its white/blacklisting, except
+# that here only envelope sender addresses are considered (not addresses
+# in a mail header), and that score points can be assigned per-recipient
+# (or globally), and the assigned penalties are customarily much lower
+# that the default SA white/blacklisting score.
+#
+# The table structure is similar to $per_recip_whitelist_sender_lookup_tables
+# i.e. the first level key is recipient, pointing to by-sender lookup tables.
+# The essential difference is that scores from _all_ by-recipient lookups

+# 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 (lists of lookup tables) are available,
+# with the semantics and syntax as specified in README.lookups:
+# @whitelist_sender_maps, @blacklist_sender_maps
+
+# SOME EXAMPLES:
+#
+#ACL:
+# @whitelist_sender_maps = ( ['.example.org', '.example.net'] );
+# @whitelist_sender_maps = ( [qw(.example.org  .example.net)] );  # same thing
+#
+# @whitelist_sender_maps = ( [".$mydomain"] );  # $mydomain and its subdomains
+# NOTE: This is not a reliable way of turning off spam checks for
+#       locally-originating mail, as sender address can easily be faked.
+#       To reliably avoid spam-scanning outgoing mail,
+#       use @bypass_spam_checks_maps .
+
+#with regexps:
+# @whitelist_sender_maps = ( new_RE(
+#   qr'^postmaster@.*\bexample\.com$'i,
+#   qr'^owner-[^@]*@'i,  qr'-request@'i,
+#   qr'\.example\.com$'i
+# ));
+
+
+# illustrates the use of regexp lookup table:
+
+@blacklist_sender_maps = ( new_RE(
+    qr'^(bulkmail|offers|cheapbenefits|earnmoney|foryou|greatcasino)@'i,

+#     find_external_programs(), which will try to find the full program
+#     path name; if program is not found, this scanner is disabled.
+w#     Besides a simple string (full program path name or just the basename
+#     to be looked for in PATH), this may be an array ref of alternative
+#     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.

+#   protocol=>'AM.PDP', # Amavis policy delegation protocol (new milter helper)
+# };
+
+## the name 'MYNETS' has special semantics: this policy bank gets loaded

+## or a new AM.PDP protocol) and that address matches the @mynetworks list.
+#
+# $policy_bank{'MYNETS'} = {  # mail originating from @mynetworks
+#   spam_kill_level_maps => 6.9,
+#   spam_admin_maps => ["spamalert\@$mydomain"],
+# };
+
+
+## Now we can assign policy banks to amavisd tcp port numbers listed in
+## $inet_socket_port. Whenever the connection from MTA is received, first
+## a built-in policy bank $policy_bank{''} gets loaded, which bringings-in
+## all the global/legacy settings, then it gets overlaid by the bank
+## named in the $interface_policy{$port} if any, and finally the bank
+## 'MYNETS' is overlaid if it exists and the SMTP client IP address
+## is known (by XFORWARD command from MTA) and it matches @mynetworks.
+
+# $interface_policy{'10026'} = 'ALT';
+# $interface_policy{'9998'} = 'AM.PDP';
