# =============== MailScanner: spam.assassin.prefs.conf ===============
# Version 2.13.1

# SpamAssassin preferences for MailScanner users should be placed in 
# this file to avoid being overwritten by a SpamAssassin upgrade.
# For a complete listing of configurable parameters, please see:

#	http://www.spamassassin.org/doc/Mail_SpamAssassin_Conf.html 

# =============== SpamAssassin Preferences ===============
# 
# the file installed by SpamAssassin: 

# 	/etc/mail/spamassassin/local.cf

# Should be disabled 
# typically use these commands:

#  mv /etc/mail/spamassassin/local.cf \
#  /etc/mail/spamassassin/local.cf.saved

# When running SpamAssassin or sa-learn from the command line, 
# or a script, you should always specify that SpamAssassin use
# this file to load SpamAssassin preferences, i.e:

# 	sa-learn --ham -p /etc/MailScanner/spam.assassin.prefs.conf \
#	--mbox ham_mbox

# 	spamassassin -D -p etc/MailScanner/spam.assassin.prefs.conf \
#	--lint

# Additional SpamAssassin rule files should be placed in:

#	/etc/mail/spamassasssin (default location)

# or in the directory specified in MailScanner.conf setting:

#	SpamAssassin Local Rules Dir =

# dns_available { yes | test[: name1 name2...] | no } (default: test)
# By default, SpamAssassin will query some default hosts on the internet 
# to attempt to check if DNS is working on not. The problem is that it can 
# introduce some delay if your network connection is down, and in some 
# cases it can wrongly guess that DNS is unavailable because the test 
# connections failed. SpamAssassin includes a default set of 13 servers, 
# among which 3 are picked randomly.

dns_available yes


# =============== White list and Black list addresses ===============

# While you can white list here but see below for a better place. 

# White list addresses should be added in

# 	/etc/MailScanner/rules/spam.whitelist.rules

# Black list addresses should be added in	

# 	/etc/MailScanner/rules/spam.blacklist.rules

# FSL Notes: we need to set the default rule for:
# Is Definitely Spam = no
# to:
# 	%rules-dir/spam.blacklist.rules
# and create a default rules-dir/spam.blacklist.rules file


# =============== OK Locales ===============  

ok_locales		en

# FSL Notes: we only support English this is unnecessary 



# =============== Bayesian Filtering ===============

# By default, the Bayesian engine is used. This is a real CPU hog 
# and uses a lot of system resources to work.
# On a small overloaded system, you might need to disable it.

# use_bayes 0

# If your root filesystem is filling up because SpamAssassin is putting
# large databases in /.spamassassin or /root/.spamassassin, you can 
# move them using the following lines to point to their new locations.
# The last part of the path is not a directory name, but actually the 
# start of the filenames. So with the settings below, the Bayes files
# will be created as /var/spool/spamassassin/bayes_msgcount, etc.

# FSL Note: we need to coordinate the Bayes File Placement
# With MailWatch

# This is actually used as a mask, not a raw chmod setting.
# Thanks for Matt Kettler for spotting this one.

# When using the scheduled Bayes expiry feature, in MailScanner.conf 
# you probably want to turn off auto-expiry in SpamAssassin as it will
# rarely complete before it is killed for taking too long. 
# You will just end up with # MailScanner: big bayes_toks.new files
# wasting space.

# FSL Note: we run Bayes expire from a cron job

# If you are using a UNIX machine with all database files on local disks,
# and no sharing of those databases across NFS filesystems, you can use a
# more efficient, but non-NFS-safe, locking mechanism.   Do this by adding
# the line "lock_method flock" to the /etc/mail/spamassassin/local.cf
# file. This is strongly recommended if you're not using NFS, as it is
# much faster than the NFS-safe locker.

lock_method flock

# The --auto-whitelist and -a options for "spamd" and "spamassassin" to
# turn on the auto-whitelist have been removed and replaced by the
# "use_auto_whitelist" configuration option which is also now turned on by
# default.

use_auto_whitelist 0


# =============== RBSL related items ===============

# By default, SpamAssassin will run RBL checks.  If your ISP already 
# does this, stop RBL checks in SpamAssassin by un-commenting  the 
# following line
# skip_rbl_checks	1

# paths to utilities
pyzor_path /usr/bin/pyzor
dcc_path /usr/bin/dccproc

# Uncomment the lines below to stop using the specific service
# To stop Razor2 checks, uncomment the following line
# use_razor2		0
# To stop DCC checks, uncomment the following line
#  use_dcc		0
# To stop Pyzor checks, uncomment the following line
#  use_pyzor	0


# The timeouts for blacklists and Razor are rather generous in the
# default state that SpamAssassin is shipped. Reducing these 
# stops a lot of timeouts from removing SpamAssassin scores 
# altogether.

rbl_timeout 20
razor_timeout 10
pyzor_timeout 10


# If you specify these scores, SpamAssassin will do RBL checks as well
# as MailScanner, which just wastes CPU power and network bandwidth.
# Either do them here by un-commenting the rules below 
# (if you have paid for them) or else uncomment the "skip_rbl_checks" # 
# line above and let MailScanner do the checks instead.

#score RCVD_IN_DUL               1

# =============== SpamAssassin Header Processing =============== 

# SpamAssassin will attempt to discover the address used in the 'MAIL FROM:' 
# phase of the SMTP transaction that delivered this message, if this data 
# has been made available by the SMTP server. This is used in the EnvelopeFrom 
# pseudo-header, and for various rules such as SPF checking.

# This should be explicitly set for MailScanner
envelope_sender_header X-MailScanner-From

# =============== Adding SpamAssassin Rules =============== 

# Add your own customized scores for some tests below.  The default
# scores are read from the installed "spamassassin.cf" file, but you
# can override or disable the here. 
# To see the list of tests and their default scores, go to 
# http://spamassassin.taint.org/tests.html 

# These next 3 lines will add a local rule to SpamAssassin to help
# protect you from the friendlygreetings.com nasty-gram which will
# send lots of spam from your PC if you let it. Not really a virus, 
# but you don't want your users all clicking on it.

# disable the ALL_TRUSTED ruleset that comes with SA 3.x.
# It's generating too many false positives

# If you have problems where ALL_TRUSTED is matching external email,
# including spam, then SpamAssassin has become confused about which hosts are
# a part of your trusted_networks. The most common cause of this is having a
# gateway mail exchanger that has a reserved IP and gets NATed by your
# firewall. Fortunately the problem is easy to fix by manually declaring a
# trusted_networks setting. See man Mail::SpamAssassin::Conf for details.
# Once manually set, SA won't try to guess.
# 
# If that does not fix your problem, the other possibility is you have an MTA
# that generates malformed Received: headers. If you've modified your
# Received: header format, please put it back to the standard format.
# SpamAssassin is quite tolerant of deviations from the RFC 2822 format, but
# there are some combinations it can't handle. If the malformed headers are
# being made by some form of network appliance that you can't fix, report a
# bug to your vendor, and as a short-term fix set the score of ALL_TRUSTED to
# 0. However, realize that other problems may occur as a result of the
# mis-parsed headers and the root cause does need fixing.
