# 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,

# Section IV - Notifications/DSN, BOUNCE/REJECT/DROP/PASS destiny, quarantine

# Select notifications text encoding when Unicode-aware Perl is converting
# text from internal character representation to external encoding (charset
# in MIME terminology). Used as argument to Perl Encode::encode subroutine.
#
#   to be used in RFC 2047-encoded header field bodies, e.g. in Subject:
#$hdr_encoding = 'iso-8859-1';  # (default: 'iso-8859-1')
#
#   to be used in notification body text: its encoding and Content-type.charset
#$bdy_encoding = 'iso-8859-1';  # (default: 'iso-8859-1')
 
# Default template texts for notifications may be overruled by directly
# assigning new text to template variables, or by reading template text
# from files. A second argument may be specified in a call to read_text(),
# specifying character encoding layer to be used when reading from the
# external file, e.g. 'utf8', 'iso-8859-1', or often just $bdy_encoding.
# Text will be converted to internal character representation by Perl 5.8.0
# or later; second argument is ignored otherwise. See PerlIO::encoding,
# Encode::PerlIO and perluniintro man pages.

#
#   read_l10n_templates('/etc/amavis/en_US');
 
 
# 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.
 
$final_virus_destiny      = D_BOUNCE;  # (defaults to D_BOUNCE)
$final_banned_destiny     = D_BOUNCE;  # (defaults to D_BOUNCE)
$final_spam_destiny       = D_BOUNCE;  # (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_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
# to D_BOUNCE.
#
# The separation of *_destiny values into D_BOUNCE, D_REJECT, D_DISCARD
# and D_PASS made settings $warnvirussender and $warnspamsender only still
# useful with D_PASS.
 
# The following $warn*sender settings are ONLY used when mail is
# actually passed to recipients ($final_*_destiny=D_PASS, or *_lovers*).
# Bounces or rejects produce non-delivery status notification anyway.
 
# Notify virus sender?
#$warnvirussender = 1; # (defaults to false (undef))
 
# Notify spam sender?
#$warnspamsender = 1; # (defaults to false (undef))

# Notify sender of syntactically invalid header containing non-ASCII characters?
#$warnbadhsender = 1; # (defaults to false (undef))
 
# Notify virus (or banned files) RECIPIENT?
#  (not very useful, but some policies demand it)
#$warnvirusrecip = 1; # (defaults to false (undef))
#$warnbannedrecip = 1; # (defaults to false (undef))
 
# Notify also non-local virus/banned recipients if $warn*recip is true?
#  (including those not matching local_domains*)
#$warn_offsite = 1; # (defaults to false (undef), i.e. only notify locals)
 
 
# Treat envelope sender address as unreliable and don't send sender
# notification / bounces if name(s) of detected virus(es) match the list.
# Note that virus names are supplied by external virus scanner(s) and are

# A finer control of quarantining is available through variable
# $virus_quarantine_to/$spam_quarantine_to. It may be a simple scalar string,
# 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
# setup, but probably not safe with sendmail milter interface without
# precaution.

# or similar may be used, which requires that at least one character precedes

# Section V - Per-recipient and per-sender handling, whitelisting, etc.

# %virus_lovers, @virus_lovers_acl and $virus_lovers_re lookup tables:
#   (these should be considered policy options, they do 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 the hash %virus_lovers, or to
# the access list @virus_lovers_acl - 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, @bypass_virus_checks_acl and $bypass_virus_checks_re
# lookup tables:
#   (this is mainly a time-saving option, unlike virus_lovers* !)
#
# Similar in concept to %virus_lovers, a hash %bypass_virus_checks,
# access list @bypass_virus_checks_acl and regexp list $bypass_virus_checks_re
# are used to skip entirely the decoding, unpacking and virus checking,
# but only if ALL recipients match the lookup.
#
# %bypass_virus_checks/@bypass_virus_checks_acl/$bypass_virus_checks_re
# do 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/@virus_lovers_acl 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 lookup tables controlling virus checking, there exist
# spam scanning, banned names/types, and headers_checks control counterparts:
#   %spam_lovers, @spam_lovers_acl, $spam_lovers_re
#   %banned_files_lovers, @banned_files_lovers_acl, $banned_files_lovers_re
#   %bad_header_lovers, @bad_header_lovers_acl, $bad_header_lovers_re
# and:
#   %bypass_spam_checks/@bypass_spam_checks_acl/$bypass_spam_checks_re
#   %bypass_banned_checks/@bypass_banned_checks_acl/$bypass_banned_checks_re
#   %bypass_header_checks/@bypass_header_checks_acl/$bypass_header_checks_re
# See README.lookups for details about the syntax.
 
# 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_acl = qw( . );
 
#   @bypass_header_checks_acl = qw( user@example.com );
#   @bad_header_lovers_acl    = qw( user@example.com );
 
 
# See README.lookups for further detail, and examples below.

# or the other way around (bypass check for all BUT these):
#   @bypass_spam_checks_acl = qw( !d1.com !.d2.com !a.d3.com . );

# Where to find SQL server(s) and database to support SQL lookups?

# If field names are not unique (e.g. 'id'), the later field overwrites the

# No need to uncomment the following assignment if the default is ok.
#   $sql_select_policy = 'SELECT *,users.id FROM users,policy'.

#
# The SQL select clause to check sender in per-recipient whitelist/blacklist
# The first SELECT argument '?' will be users.id from recipient SQL lookup,

#   $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 you decide to pass viruses (or spam) to certain recipients using the
# above lookup tables or using $final_virus_destiny=D_PASS, you can set
# the variable $addr_extension_virus ($addr_extension_spam) to some

# as an address extension to the local-part of the address. This extension
# can be used by final local delivery agent to place such mail in different
# folders. Leave these two variables undefined or empty strings to prevent
# appending address extensions. Setting has no effect on recipient which will
# not be receiving viruses/spam. Recipients who do not match lookup tables
# local_domains* are not affected.
#
# LDAs usually default to stripping away address extension if no special
# handling is specified, so having this option enabled normally does no harm,
# provided the $recipients_delimiter matches the setting on the final

# $addr_extension_virus  = 'virus'; # (default is undef, same as empty)

# (which can optionally be added, see variables $addr_extension_virus and
# $addr_extension_spam). E.g. recipient address <user@example.com> gets changed
# to <user+virus@example.com>.
#
# Delimiter should match equivalent (final) MTA delimiter setting.
# (e.g. for Postfix add 'recipient_delimiter = +' to main.cf)
# Setting it to an empty string or to undef disables this feature

# 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:
#
# %whitelist_sender, @whitelist_sender_acl, $whitelist_sender_re
# %blacklist_sender, @blacklist_sender_acl, $blacklist_sender_re
 
# SOME EXAMPLES:
#
#ACL:
# @whitelist_sender_acl = qw( .example.com );
#
# @whitelist_sender_acl = ( ".$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_acl .

# @av_scanners is a list of n-tuples, where fields semantics is:
#  1. av scanner plain name, to be used in log and reports;
#  2. scanner program name; this string will be submitted to subroutine
#     find_external_programs(), which will try to find the full program
#     path name; if program is not found, this scanner is disabled.
#     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.
