#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 = $forward_method;
# prefer to collect mail for forwarding as BSMTP files?
#$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 = 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.
$relayhost_is_client = 0; # (defaults to false)
$insert_received_line = 1; # behave like MTA: insert 'Received:' header
# (does not apply to sendmail/milter)
# (default is true (1) )
# AMAVIS-CLIENT PROTOCOL INPUT SETTINGS (e.g. with sendmail milter)
# (used with amavis helper clients like amavis-milter.c and amavis.c,
# NOT needed for Postfix and Exim or dual-sendmail - keep it undefined.)
#$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
$DO_SYSLOG = 1; # (defaults to false)
#$SYSLOG_LEVEL = 'user.info'; # (facility.priority, default 'mail.info')
# Log file (if not using syslog)
$LOGFILE = "/var/log/amavis.log"; # (defaults to empty, no log)
#NOTE: levels are not strictly observed and are somewhat arbitrary
# 0: startup/exit/failure messages, viruses detected
# 1: args passed from client, some more interesting messages
# 2: virus scanner output, timing
# 3: server, client
# 4: decompose parts
# 5: more debug details
#$log_level = 2; # (defaults to 0)
# Customizable template for the most interesting log file entry (e.g. with
# $log_level=0) (take care to properly quote Perl special characters like '\')
# For a list of available macros see README.customize .
# only log infected messages (useful with log level 0):
# $log_templ = '[? %#V |[? %#F ||banned filename ([%F|,])]|infected ([%V|,])]#
# [? %#V |[? %#F ||, from=[?%o|(?)|<%o>], to=[<%R>|,][? %i ||, quarantine %i]]#
# |, from=[?%o|(?)|<%o>], to=[<%R>|,][? %i ||, quarantine %i]]';
# log both infected and noninfected messages (default):
$log_templ = '[? %#V |[? %#F |[?%#D|Not-Delivered|Passed]|BANNED name/type (%F)]|INFECTED (%V)], #
[?%o|(?)|<%o>] -> [<%R>|,][? %i ||, quarantine %i], Message-ID: %m, Hits: %c';
#
# Section IV - Notifications/DSN, BOUNCE/REJECT/DROP/PASS destiny, quarantine
#
# Select notifications text encoding when Unicode-aware Perl is converting
# text from internal character representation to external encoding (charset
# in MIME terminology). Used as argument to Perl Encode::encode subroutine.
#
# to be used in RFC 2047-encoded header field bodies, e.g. in Subject:
#$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.
#
# $notify_sender_templ = read_text('/var/amavis/notify_sender.txt');
# $notify_virus_sender_templ= read_text('/var/amavis/notify_virus_sender.txt');
# $notify_virus_admin_templ = read_text('/var/amavis/notify_virus_admin.txt');
# $notify_virus_recips_templ= read_text('/var/amavis/notify_virus_recips.txt');
# $notify_spam_sender_templ = read_text('/var/amavis/notify_spam_sender.txt');
# $notify_spam_admin_templ = read_text('/var/amavis/notify_spam_admin.txt');
# If notification template files are collectively available in some directory,
# use read_l10n_templates which calls read_text for each known template.
#
# read_l10n_templates('/etc/amavis/en_US');
#
# Debian available locales: en_US, pt_BR, de_DE, it_IT
read_l10n_templates('en_US', '/etc/amavis');
# 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
# 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 banned files?
#$warnbannedsender = 1; # (defaults to false (undef))
# Notify sender of syntactically invalid header containing non-ASCII characters?
#$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
# not standardized, so virus names may need to be adjusted.
# See README.lookups for syntax, check also README.policy-on-notifications

# When using the 'local:' quarantine method (default), the following applies:
#
# 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.
# (the default value is undef, meaning no quarantine)
