Issue with spamassassin, now mail not working

Question

Hi ! I installed spamtrainer almost two months ago. Been feeding the [email protected] for several weeks now , 700 emails each day at least .
There was very little improvement if none at all. Tried to add "@local_domains_maps = (1)" to amavisd.conf last night thinking it might be the problem , though no virtual domain exist. This was one of the issue on the default Amavisd config. The other one is adding the symbolic link which I already done.
Computer froze while adding the parameter "@local_domains_maps = (1)", so I manually turn off the Power Mac, then mail stopped altogether. The mails are filing up but the clients couldn't send or receive since this incidence .
FF is the maincf. and amavis.conf
All help are greatly appreciated.

#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, 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 OLDER 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. Still, in both cases a backslash need 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 the string. In other words, $ and # lose their special meaning
# withing 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 nonbracketed) form, i.e.
# Bob "Funny" [email protected], not: "Bob \"Funny\" Dude"@example.com
# and not <"@example.com>; also: '' and not ''.
# 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 = 'cpplaw.com'; aol.com'; # (no useful default)
# Set the user and group to which the daemon will change if started as root
# (otherwise just keep the UID unchanged, and these settings have no effect):
$daemon_user = 'clamav'; # (no default; customary: vscan or amavis)
$daemon_group = 'clamav'; # (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?
# $helpers_home sets environment variable HOME, and is passed as option
# 'home_dir_for_helpers' to Mail::SpamAssassin::new. It should be a directory
# on a normal persistent file system, not a scratch or temporary file system
#$helpers_home = $MYHOME; # (defaults to $MYHOME)
#$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, but usually not necessary
# 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 = $forward_method; # where to submit notifications
# NOTE: The defaults (above) are good for Postfix or dual-sendmail. You MUST
# uncomment the approprate settings below if using other setups!
# SENDMAIL MILTER, using amavis-milter.c helper program:
#$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 = 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!
# 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 spacified in: $mydestination, $virtual_alias_domains,
# $virtual_mailbox_domains, and $relay_domains.
@local_domains_acl = ( ".$mydomain" ); # $mydomain and its subdomains
# @local_domains_acl = qw(); # default is empty, no recipient treated as local
# @local_domains_acl = qw( .example.com );
# @local_domains_acl = qw( .example.com !host.sub.example.net .sub.example.net );
# @local_domains_acl = ( ".$mydomain", '.example.com', '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, '/var/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, IP address in $notify_method and
# $forward_method is dynamically overridden with SMTP client peer address
# if available, which makes possible for several hosts to share one daemon
#$relayhost_is_client = 1; # (defaults to false)
#$insert_received_line = 1; # behave like MTA: insert 'Received:' header
# (does not apply to sendmail/milter)
# (default is true)
# 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)
$unix_socketname = "$MYHOME/amavisd.sock"; # amavis helper protocol socket
#$unix_socketname = undef; # disable listening on a unix socket
# (default is undef, i.e. disabled)
# (usual setting is $MYHOME/amavisd.sock)
# Do we receive quoted or raw addresses from the helper program?
# (does not apply to SMTP; defaults to true)
#$gets_addr_in_quoted_form = 1; # "Bob \"Funny\" Dude"@example.com
#$gets_addr_in_quoted_form = 0; # Bob "Funny" [email protected]
# 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
# 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
$DO_SYSLOG = 0; # (defaults to false)
#$SYSLOG_LEVEL = 'user.info'; # (defaults to '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 = 4; # (defaults to 0)
# Customizeable 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>, to=[<%R>|,][? %i ||, quarantine %i]]#
# |, from=<%o>, to=[<%R>|,][? %i ||, quarantine %i]]';
# log both infected and noninfected messages (default):
$log_templ = '[? %#V |[? %#F |[?%#D|Not-Delivered|Passed]|BANNED name/type (%F)]|INFECTED (%V)], #
<%o> -> [<%R>|,][? %i ||, quarantine %i], Message-ID: %m, Hits: %c';
# Section IV - Notifications/DSN, BOUNCE/REJECT/DROP/PASS destiny, quarantine
# Select notifications text encoding when Unicode-aware Perl is converting
# text from internal character representation to external encoding (charset
# in MIME terminology)
# to be used in RFC 2047-encoded header field bodies, e.g. in Subject:
#$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_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');
# 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). Not a decent thing to do for a mailer.
# 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_PASS; # (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;
# There are no sensible alternatives to D_BOUNCE 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 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.

# 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 containg 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 unecessarily 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

# %virus_lovers, @virus_lovers_acl and $virus_lovers_re lookup tables:
# (these should be considered policy options, they do not disable checks,
# see bypas*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( [email protected] );
# @bad_header_lovers_acl = qw( [email protected] );
# See README.lookups for further detail, and examples below.

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

# $sql_select_policy = 'SELECT *,users.id FROM users,policy'.
# ' WHERE (users.policy_id=policy.id) AND (users.email IN (%k))'.

# ' WHERE (rid=?) AND (sid=mailaddr.id) AND (mailaddr.email IN (%k))'.
# ' ORDER BY mailaddr.priority DESC';

# If you decide to pass viruses (or spam) to certain recipients using the

# 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

# Delimiter should match equivalent (final) MTA delimiter setting.

# ENVELOPE SENDER WHITELISTING / BLACKLISTING - GLOBAL (RECIPIENT-INDEPENDENT)
# WHITELISTING: use ENVELOPE SENDER lookups to ENSURE DELIVERY from whitelisted
# senders even if the message is recognized as spam. Effectively, for the
# specified senders, message RECIPIENTS temporarily become 'spam_lovers', with
# further processing being the same as otherwise specified for spam lovers.
# It does not turn off inserting spam-related headers, if they are enabled.
# 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 tagged as spam.
# 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"
# 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 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;
# CORROLARY: 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.

Answer 1

You are welcome. I'm glad you got it back up.
(1) You say you did the symbolic link. I will assume this is set correctly; it's very important that it is.
(2) I don't know what you mean by "Been feeding the [email protected] for several weeks now, 700 emails each day at least." After the initial training period, SpamAssassin doesn't learn from mail it has already processed correctly. At this point, you only need to teach SpamAssassin when it is wrong. [email protected] should only be getting spam that is being passed as clean. Likewise, [email protected] should only be getting legitimate mail that is being flagged as junk. You are redirecting mail to both [email protected] and [email protected] ... right? SpamAssassin needs both.
(3) Next, as I said before, you need to implement those "Frontline spam defense for Mac OS X Server." Once you have that done and issue "postfix reload" you can look at your SMTP log in Server Admin and watch as Postfix blocks one piece of junk mail after another. It's kind of cool.
(4) Add some SARE rules:
Visit http://www.rulesemporium.com/rules.htm and download the following rules:
70sareadult.cf
70saregenlsubj0.cf
70sareheader0.cf
70sarehtml0.cf
70sareobfu0.cf
70sareoem.cf
70sarespoof.cf
70sarestocks.cf
70sareunsub.cf
72sare_redirectpost
Visit http://www.rulesemporium.com/other-rules.htm and download the following rules:
backhair.cf
bogus-virus-warnings.cf
chickenpox.cf
weeds.cf
Copy these rules to /etc/mail/spamassassin/
Then stop and restart mail services.
There are other things you can do, and you'll find differing opinions about such things. In general, I think implementing the "Frontline spam defense for Mac OS X Server" and adding the SARE rules will help a lot. Good luck!
