 +#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 = 'ubuntu.oriol.joor.net';      # (no useful default)
 +
 +# $myhostname = 'host.example.com';  # fqdn of this host, default by uname(3)
 +$myhostname='ubuntu.oriol.joor.net';
 +
 +# 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 = $forward_method;
 +
 +# prefer to collect mail for forwarding as BSMTP files?
 +#$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  = 10;   # number of pre-forked children          (default 2)
 +$max_requests = 20;   # retire a child after that many accepts (default 10)
 +
 +$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
 +# $forward_method is dynamically overridden with SMTP client peer address
 +# (if available), which makes it possible for several hosts to share one 
 +# daemon.  The static port number is also overridden, and is dynamically 
 +# calculated  as being one above the incoming SMTP/LMTP session port number.
 +#
 +# These are logged at level 3, so enable logging until you know you got it
 +# right.
 +$relayhost_is_client = 0;         # (defaults to false)

 +
 +# 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

 +#   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 );

 +# 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.

 +# 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
 +# to D_BOUNCE.
 +#
 +# The separation of *_destiny values into D_BOUNCE, D_REJECT, D_DISCARD

 +# $virus_quarantine_to/$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.

 +#
 +# 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

 +# (header not inserted with milter interface!)
 +#
 +# NOTE (milter interface only): in case of multiple recipients,

 +# 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

 +# 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

 +read_hash(\%whitelist_sender, '/etc/amavis/whitelist');
 +read_hash(\%blacklist_sender, '/etc/amavis/blacklist');
 +read_hash(\%spam_lovers, '/etc/amavis/spam_lovers');
 +
 +
 +
 +# 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 .
 +
 +#RE:
 +# $whitelist_sender_re = new_RE(

 +#HASH lookup variant:
 +# NOTE: Perl operator qw splits its argument string by whitespace

 +# e.g. map {...} ('one user@bla', '.second.com'), or use read_hash to read
 +# addresses from a file.
 +#

 +# @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.
