I want to have a server (call it "spamgate") that can: 1. Score and tag ALL inbound mail with Spamassassin headers, whether it be deemed spam, virus or perfectly legitimate email.
2. Deliver NO mail locally but relay ALL mail to a single destination or host (sadly, an Exchange machine.) 3. Accept mail for three domains only, all of which are owned and managed by our organization. All three domains have the same (Exchange server) host/destination. 4. For now, the spamgate box will not quarantine, reject or delete ANYTHING on the basis of it being spam ------------------------- amavisd.conf ----------------------- use strict; # Modified for use with Debian by Gary V, mr88talent at yahoo dot com # a minimalistic configuration file for amavisd-new with all necessary settings # For use with amavisd-new 2.4.3 (and possibly newer) # # see amavisd.conf-default for a list of all variables with their defaults; # see amavisd.conf-sample for a traditional-style commented file; # for more details see documentation in INSTALL, README_FILES/* # and at http://www.ijs.si/software/amavisd/amavisd-new-docs.html # COMMONLY ADJUSTED SETTINGS: @bypass_virus_checks_maps = (1); # uncomment to DISABLE anti-virus code @local_domains_acl = ( ".$mydomain" ); $max_servers = 4; # number of pre-forked children (2..15 is common), -m $daemon_user = 'amavis'; # (no default; customary: vscan or amavis), -u $daemon_group = 'amavis'; # (no default; customary: vscan or amavis), -g $mydomain = 'powersteeringsoftware.com'; # a convenient default for other settings $myhostname = 'monhegan.cinteractive.com'; # must be a fully-qualified domain name! $MYHOME = '/var/lib/amavis'; # a convenient default for other settings, -H $TEMPBASE = "$MYHOME"; # working directory, needs to exist, -T $ENV{TMPDIR} = $TEMPBASE; # environment variable TMPDIR $QUARANTINEDIR = '/var/lib/amavis/virusmails'; # -Q # $quarantine_subdir_levels = 1; # add level of subdirs to disperse quarantine $X_HEADER_LINE = "by $myversion (Debian) at $mydomain"; # $daemon_chroot_dir = $MYHOME; # chroot directory or undef, -R $db_home = "$MYHOME/db"; # dir for bdb nanny/cache/snmp databases, -D $helpers_home = "$MYHOME/var"; # working directory for SpamAssassin, -S $lock_file = "/var/run/amavis/amavisd.lock"; # -L $pid_file = "/var/run/amavis/amavisd.pid"; # -P #NOTE: create directories $MYHOME/tmp, $MYHOME/var, $MYHOME/db manually [EMAIL PROTECTED] = ( [".$mydomain"] ); [EMAIL PROTECTED] = ( [".$psteering.com" , ".$cinteractive.com" , ".$powersteeringsoftware.com"] ); @local_domains_maps = ( [qw( .psteering.com .powersteeringsoftware.com .cinteractive.com )] ); [EMAIL PROTECTED] = qw( 127.0.0.0/8 [::1] [FE80::]/10 [FEC0::]/10 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 ); $log_level = 5; # verbosity 0..5, -d $log_recip_templ = undef; # disable by-recipient level-0 log entries $DO_SYSLOG = 1; # log via syslogd (preferred) $syslog_facility = 'mail'; # Syslog facility as a string # e.g.: mail, daemon, user, local0, ... local7 $syslog_priority = 'debug'; # Syslog base (minimal) priority as a string, # choose from: emerg, alert, crit, err, warning, notice, info, debug $enable_db = 1; # enable use of BerkeleyDB/libdb (SNMP and nanny) $enable_global_cache = 1; # enable use of libdb-based cache if $enable_db=1 $inet_socket_port = 10024; # listen on this local TCP port(s) (see $protocol) $unix_socketname = "$MYHOME/amavisd.sock"; # amavisd-release or amavis-milter # option(s) -p overrides $inet_socket_port and $unix_socketname $interface_policy{'SOCK'}='AM.PDP-SOCK'; # only relevant with $unix_socketname # Use with amavis-release over a socket or with Petr Rehor's amavis-milter.c # (with amavis-milter.c from this package or old amavis.c client use 'AM.CL'): $policy_bank{'AM.PDP-SOCK'} = { protocol => 'AM.PDP', auth_required_release => 0, # don't require secret-id for release }; $sa_tag_level_deflt = undef; # add spam info headers if at, or above that level # $sa_tag_level_deflt = undef; # add spam info headers if at, or above that level $sa_tag2_level_deflt = 5.0; # add 'spam detected' headers at that level $sa_kill_level_deflt = 9999; $sa_kill_level_deflt = 8.0; $sa_dsn_cutoff_level = 10; # spam level beyond which a DSN is not sent # $sa_quarantine_cutoff_level = 20; # spam level beyond which quarantine is off # $penpals_bonus_score = 4; # (no effect without a @storage_sql_dsn database) # $penpals_threshold_high = $sa_kill_level_deflt; # don't waste time on hi spam $sa_mail_body_size_limit = 400*1024; # don't waste time on SA if mail is larger $sa_local_tests_only = 1; # only tests which do not require internet access?
