+
+#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 can represent 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;
+# Note that this interpretation of boolean values does not apply directly
+# to LDAP and SQL lookups, which follow their own rules - see README.lookups
+# and README.ldap (in short: use Y/N in SQL, and TRUE/FALSE in LDAP);
+# - Perl syntax applies. Most notably: strings in "" may include variables
+# (which start with $ or @@); to include characters $ and @@ 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.
+# In both types of quoting a backslash should to be doubled.
+# - variables with names starting with a '@@' are lists, the values assigned
+# to them should be lists too, 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

+#
+# 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_maps, or to messages from mailing lists
+# (Precedence: bulk|list|junk), or for spam level that exceeds
+# the $sa_dsn_cutoff_level.
+#
+# 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).
+# Not to be used with Postfix or dual-MTA setups!
+#
+# 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 and Courier, especially for spam.
+# With D_BOUNCE, amavisd-new (not MTA) sends DSN (can better explain the
+# reason for mail non-delivery or even suppress DSN, 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.
+
+# Alternatives to consider for spam:
+# - use D_PASS if clients will do filtering based on inserted
+# mail headers or added address extensions ('plus-addressing');
+# - use D_DISCARD, if kill_level is set comfortably high;
+#
+# D_BOUNCE is preferred for viruses, but consider:
+# - use D_PASS (or virus_lovers) to deliver viruses;
+# - use D_REJECT instead of D_BOUNCE if using Courier or milter and under heavy
+# virus storm;
+
+
+# The use of new *_by_ccat hashes is illustrated by the following examples
+# on configuring final_*_destiny.
+
+
+# using traditional settings of $final_*_destiny variables, relying on a
+# default setting of an associative array %final_destiny_by_ccat which is
+# backwards compatible and contains references to these traditional variables:
+#
+$final_virus_destiny = D_REJECT; # (defaults to D_DISCARD)
+$final_banned_destiny = D_REJECT; # (defaults to D_BOUNCE)
+$final_spam_destiny = D_REJECT; # (defaults to D_BOUNCE)
+$final_bad_header_destiny = D_PASS; # (defaults to D_PASS)
+
+########
+#
+# 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, causing the bounces to go to innocent parties,
+# whose addresses have been forged.
+#
+# 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.

+# 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 variant enables more refined delivery control made available by MTA

+# 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

+# 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 envelope sender addresses, 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 or may not have 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:
