# Main configuration file for the MailScanner Email Processor
#
# READ THIS FIRST!
# Instead of making changes directly to this file, you should put your
# configuration options in your own file in /etc/MailScanner/conf.d/
# Example file: /etc/MailScanner/conf.d/my_settings.conf
# However, if you are changing some variable definition which is used
# in other definitions in this file such as %org-name% in the first
# example below, you must also either change it in this file or copy
# all the definitions that use that variable into your own file.
# 
# Examples:
#
#	%org-name% = foobar
#	Max Children = 30
#	Incoming Queue Dir = /var/spool/mqueue.in
#
# READ THIS TOO!
# In addition to this file you must also set your preferences in:
#
# /etc/MailScanner/defaults
#
# It's good practice to check through configuration files to make sure
# they fit with your system and your needs, whatever you expect them to
# contain.
#
# Note: If your directories are symlinked (soft-linked) in any way,
#       please put their *real* location in here, not a path that
#       includes any links. You may get some very strange error
#       messages from some of the virus scanners if you don't.
#
# Note for Version 4.00 and above:
#       A lot of the settings can take a ruleset as well as just simple
#       values. These rulesets are files containing rules which are applied
#       to the current message to calculate the value of the configuration
#       option. The rules are checked in the order they appear in the ruleset.
#
# Note for Version 4.03 and above:
#       As well as rulesets, you can now include your own functions in
#       here. Look at the directory containing Config.pm and you will find
#       CustomConfig.pm. In here, you can add your own "value" function and
#       an Initvalue function to set up any global state you need such as
#       database connections. Then for a setting below, you can put:
#               Configuration Option = &ValueFunction
#       where "ValueFunction" is the name of the function you have
#       written in CustomConfig.pm.
#
# Note for Version 4.54 and above:
#       Numbers can be scaled by 1 thousand, 1 million or 1 billion by
#       putting a "k", "m" or "g" immediately after the number. You must
#       *not* put any spaces between the number and the k, m or g.
#
# Note for Version 4.77 and above:
#	If you are going to use "host:" in rulesets, it is imperative that
#	you have a local caching name-server (DNS server). Or else using
#	"host:" in rulesets will really slow you down.
#
# Note for Version 4.78 and above:
#       This file now supports nested "include" statements. The syntax is
#       include filename-wildcard-here
#       where filename-wildcard-here is replaced with the full path of one
#       or more other MailScanner.conf files to be read. You can use the
#       normal shell wildcard characters such as "*".
#       For each setting, the last value read will be used by MailScanner.
#       At the end of this file, there is an "include" that will pull in
#       all the files in /etc/MailScanner/conf.d so you can just add
#       your own local changes in there, and not need to modify this file.
#

#
# Definition of variables which are substituted into definitions below.
#
# You can add any %variables% that you want to use in addition to the
# ones provided.
#
# You can also use any shell environment variables here such as $HOSTNAME
# or ${HOSTNAME} in configuration settings and rulesets. See the
# definition of "Hostname" for an example.
#

# Enter a short identifying name for your organisation below, this is
# used to make the X-MailScanner headers unique for your organisation.
# Multiple servers within one site should use an identical value here
# to avoid adding multiple redundant headers where mail has passed
# through several servers within your organisation.
#
# Note: Some Symantec scanners complain (incorrectly) about "."
# ***** characters appearing in the names of headers.
#       Some other mail servers complain about "_" characters
#       appearing in the names of headers as well.
#       So don't put "." or "_" in this setting.

# Incoming Work Dir Settings
# --------------------------
#
# You should not normally need to touch these settings at all,
# unless you are using ClamAV and need to be able to use the
# external archive unpackers instead of ClamAV's built-in ones.

# If you want to create the temporary working files so they are owned
# by a user other than the "Run As User" setting at the top of this file,
# you can change that here.
#
# Note: If the "Run As User" is not "root" you cannot change the
#       user but may still be able to change the group, if the
#       "Run As User" is a member of both of the groups "Run As Group"
#       and "Incoming Work Group"
# Note: If the "Run As User" is "root" (or not set at all) and you are
#       using the "clamd" virus scanner AND clamd is not running as root,
#       then this must be set to the group clamd is using (from your
#       clamd.conf), example:
#       Incoming Work Group = mtagroup
#       Incoming Work Permissions = 0660
#
#		The installer creates a group on your system called "mtagroup"
#		and adds found users from mail, clamav, postfix, exim, etc
#		to that group. This combined with Incoming Work Permissions
#		of 0660 allows file access without errors such as the 
#		infamous ClamAV ./lstat() error.
Incoming Work User =
Incoming Work Group = mtagroup

# If you want processes running under the same *group* as MailScanner to
# be able to read the working files (and list what is in the
# directories, of course), set to 0640. If you want *all* other users to
# be able to read them, set to 0644. For a detailed description, if
# you're not already familiar with it, refer to `man 2 chmod`.
# Typical use: external helper programs of virus scanners (notably ClamAV),
# like unpackers.
# Use with care, you may well open security holes.
#
# Note: If the "Run As User" is "root" (or not set at all) and you are
#       using the "clamd" virus scanner, add the clam daemon user to 
#		the group "mtagroup" and set:
#       Incoming Work Group = mtagroup
#       Incoming Work Permissions = 0660
#
#		0660 is useful for using a group to allow permissions across
#		your MTA and virus scanners. the installer creates mtagroup		
#		and adds found users (clamav, postfix, mail, exim) to that 
#		group during the install process
Incoming Work Permissions = 0660

#
# Quarantine and Archive Settings
# -------------------------------
#
# If, for example, you are using a web interface so that users can manage
# their quarantined files, you might want to change the ownership and
# permissions of the quarantined so that they can be read and/or deleted
# by the web server.
# Don't touch this unless you know what you are doing!

# If you want to create the quarantine/archive so the files are owned
# by a user other than the "Run As User" setting at the top of this file,
# you can change that here.
# Note: If the "Run As User" is not "root" then you cannot change the
#       user but may still be able to change the group, if the
#       "Run As User" is a member of both of the groups "Run As Group"
#       and "Quarantine Group".

# If you want processes running under the same *group* as MailScanner to

#
# Processing Incoming Mail
# ------------------------
#

# In every batch of virus-scanning, limit the maximum
# a) number of unscanned messages to deliver
# b) number of potentially infected messages to unpack and scan
# c) total size of unscanned messages to deliver
# d) total size of potentially infected messages to unpack and scan

Max Unscanned Bytes Per Scan = 100m
Max Unsafe Bytes Per Scan = 50m
Max Unscanned Messages Per Scan = 30
Max Unsafe Messages Per Scan = 30

# If more messages are found in the queue than this, then switch to an
# "accelerated" mode of processing messages. This will cause it to stop
# scanning messages in strict date order, but in the order it finds them
# in the queue. If your queue is bigger than this size a lot of the time,
# then some messages could be greatly delayed. So treat this option as
# "in emergency only".
Max Normal Queue Size = 800

# If this is set to "yes", then email messages passing through MailScanner
# will be processed and checked, and all the other options in this file
# will be used to control what checks are made on the message.
#
# If this is set to "no", then email messages will NOT be processed or
# checked *at all*, and so any viruses or other problems will be ignored.
#
# If this is set to "virus", then email messages will only be scanned for
# viruses and *nothing* else.
#
# The purpose of this option is to set it to be a ruleset, so that you
# can skip all scanning of mail destined for some of your users/customers
# and still scan all the rest.
# A sample ruleset would look like this:
#   To:       bad.customer.com  no
#   From:     ignore.domain.com no
#   From:     my.domain.com     virus
#   FromOrTo: default           yes
# That will scan all mail except mail to bad.customer.com and mail from
# ignore.domain.com. To set this up, put the 3 lines above into a file
# called /etc/MailScanner/rules/scan.messages.rules and set the next line to
# Scan Messages = %rules-dir%/scan.messages.rules
# This can also be the filename of a ruleset (as illustrated above).
Scan Messages = yes

# You may not want to receive mail from certain addresses and/or to certain
# addresses. If so, you can do this with your email transport (sendmail,
# Postfix, etc) but that will just send a one-line message which is not
# helpful to the user sending the message.
# If this is set to yes, then the message set by the "Rejection Report"
# will be sent instead, and the incoming message will be deleted.
# If you want to store a copy of the original incoming message then use the
# "Archive Mail" setting to archive a copy of it.
# The purpose of this option is to set it to be a ruleset, so that you
# can reject messages from a few offending addresses where you need to  send
# a polite reply instead of just a brief 1-line rejection message.
Reject Message = no

# Limit the number of attempts made at processing any particular message.
# If you get a message which repeatedly crashes MailScanner, it will
# limit the impact by ignoring the message and refusing to process it,
# after more than the given number of attempts have been made at it.
# Note that enabling this feature causes a slight performance hit.
# Set this to 0 to disable the limit and the entire Processing Attempts
# Database and its requirement for SQLite.

# if they are not using Microsoft Outlook.
#
# no      => Leave winmail.dat TNEF attachments alone.
# add     => Add the contents of winmail.dat as extra attachments, but also

#            TNEF messages being doubled in size.
# replace => Replace the winmail.dat TNEF attachment with the files it
#            contains, and delete the original winmail.dat file itself.

#
# Attachment Filename Checking
# ----------------------------
#

# There are now 2 sets of configurations for filename and filetype checking.
# One set applies to files found within attachments which are archives,
# their names start with "Archives:".
# The other set of configuration options applies to normal attachments,
# their names do *not* start with "Archives:".

# What sort of attachments are considered to be archives?
# You may well consider, for example, zip and rar files to be archives, but
# maybe TNEF files to not be archives as they are really just another way
# of supplying attachments that is only used by Microsoft Exchange and Outlook.
# This is a space-separated list of the types which are treated as archives.
# Valid keywords within this are:
#       zip  -- Zip files and Microsoft Office 2007 documents
#       rar  -- Rar archives
#       uu   -- UU-encoded files
#       ole  -- Microsoft ".doc" and ".xls" and ".ppt" files
#       tnef -- "winmail.dat" files created by Microsoft Exchange or Outlook
Archives Are = zip rar ole

# To simplify web-based configuration systems, there are now two extra
# settings here. They are both intended for use with normal rulesets
# that you would expect to find in %rules-dir%. The first gives a list
# of patterns to match against the attachment filenames, and a filename
# is allowed if it matches any of these patterns. The second gives the
# the equivalent list for patterns that are used to deny filenames.
# If either of these match at all, then filename.rules.conf is ignored
# for that filename.
# So you can easily have a set like this:
# Allow Filenames = \.txt$ \.pdf$
# Deny  Filenames = \.com$ \.exe$ \.cpl$ \.pif$
# which is a lot simpler than having to handle filename.rules.conf!
# It is far simpler when you want to change the allowed+denied list for
# different domains/addresses, as you can use the filename of a simple
# ruleset here instead.
# NOTE: The filename and filetype rules are separate, so if you want to
#       allow executable *.exe files you will need at least
#           Allow Filenames = \.exe$
#           Allow Filetypes = executable
#       to make it pass both tests. If either test denies the attachment
#       then it will be blocked.

# Allow any attachment filenames matching any of the patterns listed here.
# If this setting is empty, it is ignored and no matches are made.
# This can also be the filename of a ruleset.
Allow Filenames =

# Deny any attachment filenames matching any of the patterns listed here.
# If this setting is empty, it is ignored and no matches are made.
# This can also be the filename of a ruleset.
Deny Filenames =

# 
# Set where to find the attachment filename ruleset.
# The structure of this file is explained elsewhere, but it is used to
# accept or reject file attachments based on their name, regardless of
# whether they are infected or not.
#
# This can also point to a ruleset, but the ruleset filename must end in
# ".rules" so that MailScanner can determine if the filename given is
# a ruleset or not!

# is allowed if it matches any of these patterns. The second gives the
# the equivalent list for patterns that are used to deny filetypes.
# If either of these match at all, then filetype.rules.conf is ignored
# for that filetype.
# So you can easily have a set like this:
# Allow Filetypes = script postscript
# Deny  Filetypes = executable MPEG
# Allow MIME Filetypes = text/plain text/html
# Deny  MIME Filetypes = dosexec

# by the "file" command, regardless of whether they are infected or not.
#
# This can also point to a ruleset, but the ruleset filename must end in
# ".rules" so that MailScanner can determine if the filename given is
# a ruleset or not!
#
# To disable this feature, set this to just "Filetype Rules =" or set
# the location of the file command to a blank string.
Filetype Rules = %etc-dir%/filetype.rules.conf

# In the "Filename Rules" and "Filetype Rules" rule files, you can
# say that you want particular attachment names or types to be "disarmed"
# by being renamed. See the sample files for examples of this.
#
# The "rename" rules in filetype.rules.conf rename attachments that match
# the rule according to this setting, where the string "__FILENAME__" will
# be replaced with the attachment's original filename.
#
# In filename.rules.conf, it is a little more complex. They can work just
# like the filetype rules.conf version explained in the previous paragraph,
# or else the "rename" instruction can also supply the replacement text.
# For example, a rule starting
# rename to .txt	\.reg$	.....
# will match all attachment filenames ending in ".reg" and replace the
# ".reg" with ".txt".
#
# The "rename" rules change the filename of the attachment as described
# above, so that either
# (a) the user cannot simply double-click on the attachment, but must save
#     it then rename it back to its original name; only then can they
#     double-click on the file.
# OR
# (b) the action taken when the user double-clicks on the file will be
#     changed. In the "reg"/"txt" example above, the file will be opened
#     for editing rather than immediately merged into the user's Windows
#     Registry, which could have had disastrous consequences.
#
# This provides a simple safeguard so that users have to consciously
# think about what they are doing, and do not accidentally take actions
# they would probably regret. In some situations this is better than
# just denying the file completely, as the user can still see the attachment
# they were sent.
#
# This can also be the filename of a ruleset.

# Setting this enables delivery error messages to be identified as yours

# If it is set to "delete", then the message is deleted and no further action
# is taken.
# If it is set to a number, then that is added to the message's spam score
# and it's spam status is updated accordingly.
# If you set it to "nothing" then there probably isn't much
# point in checking watermarks at all. But it could still be useful in
# rulesets and Custom Functions.
# This can also be the filename of a ruleset.
Treat Invalid Watermarks With No Sender as Spam = nothing

# Enable this feature if you have more then one Mailscanner installation

# This could be achieved by using a ruleset.
#
# This feature skips Spam Checks if the Watermark is trusted. The trust

# SpamAssassin
# ------------
#

# Do you want to find spam using the "SpamAssassin" package?
# This can also be the filename of a ruleset.
Use SpamAssassin = yes

# SpamAssassin is not very fast when scanning huge messages, so messages
# bigger than this value will be truncated to this length for SpamAssassin
# testing. The original message will not be affected by this. This value
# is a good compromise as very few spam messages are bigger than this.
#
# Now for the options:
# 1) <length of data in bytes>
# 2) <length of data in bytes> trackback
# 3) <length of data in bytes> continue <max extra bytes allowed>
#
# 1) Put in a simple number.
#    This will be the simple cut-off point for messages that are larger than
#    this number.
# 2) Put in a number followed by 'trackback'.
#    Once the size limit is reached, MailScanner reverses towards the start
#    of the message, until it hits a line that is blank. The message passed
#    to SpamAssassin is truncated there. This stops any part-images being
#    passed to SpamAssassin, and so avoids rules which trigger on this.
# 3) Put in a number followed by 'continue' followed by another number.
#    Once the size limit is reached, MailScanner continues adding to the data
#    passed to SpamAssassin, until at most the 2nd number of bytes have been
#    added looking for a blank line. This tries to complete the image data
#    that has been started when the 1st number of bytes has been reached,
#    while imposing a limit on the amount that can be added (to avoid attacks).
#
# If all this confuses you, just leave it alone at "40k" as that is good.
Max SpamAssassin Size = 200k

# This replaces the SpamAssassin configuration value 'required_hits'.
# If a message achieves a SpamAssassin score higher than this value,
# it is spam. See also the High SpamAssassin Score configuration option.
# This can also be the filename of a ruleset, so the SpamAssassin
# required_hits value can be set to different values for different messages.

# If a message achieves a SpamAssassin score higher than this value,

High SpamAssassin Score = 10

# Set this option to "yes" to enable the automatic whitelisting functions
# available within SpamAssassin. This will cause addresses from which you

# messages from those addresses.
# To disable whitelisting, you must set "use_auto_whitelist 0" in your
# spamassassin.conf file as well as set this to no.
SpamAssassin Auto Whitelist = yes

# If SpamAssassin takes longer than this (in seconds), the check is
# abandoned and the timeout noted.
SpamAssassin Timeout = 75

# This means that remote network failures causing SpamAssassin trouble will
# not mean your mail stops flowing.
Max SpamAssassin Timeouts = 10

# The total number of SpamAssassin attempts during which "Max SpamAssassin
# Timeouts" will cause SpamAssassin to stop doing all network-based tests.
# If double the timeout value is reached (i.e. it continues to timeout at
# the same frequency as before) then it is marked as "unavailable".
# See the previous comment for more information.
# The default values of 10 and 20 mean that 10 timeouts in any sequence of
# 20 attempts will trigger the behaviour described above, until the next

SpamAssassin Timeouts History = 30

# If the message sender is on any of the Spam Lists, do you still want

# This can also be the filename of a ruleset.
Check SpamAssassin If On Spam List = yes

# Normally, SpamAssassin skips over all non-text attachments and does not
# scan them for indications that the message is spam.
# This setting over-rides that behaviour, telling SpamAssassin to scan all
# attachments regardless of type. This can be very useful for spotting rude
# and derogatory content in Microsoft Word documents, for example.
# However, it does slightly slow SpamAssassin and so is disabled by default.

Include Binary Attachments In SpamAssassin = no

# Do you want to include the "Spam Score" header. This shows 1 character

# Custom Spam Scanner Plugin
# --------------------------
#

# Use the Custom Spam Scanner. This is code you will have to write yourself,
# a function called "GenericSpamScanner" stored in the file
# MailScanner/lib/MailScanner/CustomFunctions/GenericSpamScanner.pm
# It will be passed
#  $IP      - the numeric IP address of the system on the remote end
#             of the SMTP connections
#  $From    - the address of the envelope sender of the message
#  $To      - a perl reference to the envelope recipients of the message
#  $Message - a perl reference to the list of line of the message
# A sample function is given in the correct file in the distribution.
# This sample function also includes code to show you how to make it run
# an external program to produce a spam score.
# This can also be the filename of a ruleset.
Use Custom Spam Scanner = no

# How much of the message should be passed to the Custom Spam Scanner.
# Most spam tools only need the first 20kbytes of the message to determine
# if it is spam or not. Passing more than is necessary only slows things
# down.
# This can also be the filename of a ruleset.
Max Custom Spam Scanner Size = 20k

# How long should the custom spam scanner take to run? If it takes more
# seconds than this, then it should be considered to have crashed and
# should be killed. This stops denial-of-service attacks.
Custom Spam Scanner Timeout = 20

# If the Custom Spam Scanner times out more times in a row than this,
# then it will be marked as "unavailable" until MailScanner next re-
# starts itself.
Max Custom Spam Scanner Timeouts = 10

# The total number of Custom Spam Scanner attempts during which "Max
# Custom Spam Scanner Timeouts" will cause the Custom Spam Scanner to
# be marked as "unavailable". See the previous comment for more information.
# The default values of 10 and 20 mean that 10 timeouts in any sequence of

#
# What to do with spam
# --------------------
#

# This is a list of actions to take when a message is spam.
# It can be any combination of the following:
#    deliver                 - deliver the message as normal
#    delete                  - delete the message
#    store                   - store the message in the (spam) quarantine
#    store-nonmcp            - store the message in the non-MCP quarantine
#    store-mcp               - store the message in the MCP quarantine
#    store-nonspam           - store the message in the non-spam quarantine
#    store-spam              - store the message in the spam quarantine
#    store-<directory-path>  - store the message in the <directory-path>
#    bounce                  - send a rejection message back to the sender
#    forward user@domain.com - forward a copy of the message to user@domain.com
#                              See the note below about the keywords that
#                              can be used.
#    striphtml               - convert all in-line HTML content to plain text.
#                              You need to specify "deliver" as well for the
#                              message to reach the original recipient.
#    attachment              - Convert the original message into an attachment
#                              of the message. This means the user has to take
#                              an extra step to open the spam, and stops "web
#                              bugs" very effectively.
#    notify                  - Send the recipients a short notification that
#                              spam addressed to them was not delivered. They
#                              can then take action to request retrieval of
#                              the original message if they think it was not
#                              spam.
#    header "name: value"    - Add the header
#                                name: value
#                              to the message. name must not contain any spaces.
#                              The "value" may contain the magic keyword "_TO_"
#                              anywhere in it. _TO_ will be replaced by a
#                              comma-separated list of the original recipients
#                              of the message. This is very useful if you just
#                              forward the message to a new address and don't
#                              use the "deliver" action, as otherwise the list
#                              of the original recipients may be lost.
#    custom(parameter)       - Call the CustomAction function in /usr/lib/Mail-
#                              Scanner/MailScanner/CustomFunctions/CustomAction
#                              .pm with the 'parameter' passed in. This can be
#                              used to implement any custom action you require.
#
# "forward" keywords
# ==================
# In an email address specified in the "forward" action, several keywords can
# be used which will be substituted with various properties of the message:
# _FROMUSER_   The left-hand side of the address of the sender.
# _FROMDOMAIN_ The right-hand side of the address of the sender.
# _TOUSER_     The left-hand side of each of the recipients in turn.
# _TODOMAIN_   The right-hand side of each of the recipients in turn.
# _DATE_       The date the message was received by MailScanner.
# _HOUR_       The hour the message was received by MailScanner.
# This means that you can forward messages to email addresses which show the
# original recipients of the message, which could be very useful when
# delivering into spam archive management systems.
#
# The default value I have set here enables Thunderbird to automatically
# handle spam when set to trust the "SpamAssassin" headers.
#
# This can also be the filename of a ruleset, in which case the filename
# must end in ".rule" or ".rules".

Non Spam Actions = deliver header "X-Spam-Status: No"

# This next setting is very powerful. It allows you to adjust the list of
# actions taken on a message by adding or removing any action or actions,
# depending on what SpamAssassin rules it matched.
# It can be used to replace the functionality of MCP, but without the large
# processing overhead that involves.
#
# The setting consists of a comma-separated list of
# SA_RULENAME=>action,action,...
# pairs, where 'SA_RULENAME' is the name of any SpamAssassin rule (or
# meta-rule), and 'action' is the name of any of the actions listed above
# the 'Spam Actions' configuration setting or the word "not-" preceding any
# of the action names.
# Preceding the action name with "not-" as in "not-deliver" or "not-forward
# user@domain.com" will cause the action to be removed from the list of
# actions that would normally be taken on this message.
#
# All of the keywords available in the "forward" action also work here.
#
# You can specify a comma-separated list of actions if you need more than 1
# action per rule.
#
# Example: Setting this to
# SpamAssassin Rule Actions = FROM_BOSS_WIFE=>not-forward secretary@domain.com
# would result in mail from the boss's wife not being forwarded to the boss's
# secretary, which would be useful if the non-spam actions for the message
# included forwarding to the boss's secretary.
#
# You can also trigger actions on the spam score of the message. You can
# compare the spam score with a number and cause this to trigger an action.
# For example, instead of a SA_RULENAME you can specify
# SpamScore>number or SpamScore>=number or SpamScore==number or
# SpamScore<number or SpamScore<=number
# where "number" is the threshold value you are comparing it against.
# So you could have a rule/action pair that looks like
#                  SpamScore>25=>delete
# This would cause all messages with a total spam score of more than 25 to be
# deleted. You can use this to implement multiple levels of spam actions in
# addition to the normal spam actions and the high-scoring spam actions.
#
# Combining this with a ruleset makes it even more powerful, as different
# recipients and/or senders can have different sets of rules applied to them.
#
# This can also be the filename of a ruleset, in which case the filename
# must end in ".rule" or ".rules".

# Database SQL Configuration Settings
#
# This section allows you to over-ride any setting in this file or its
# related "include"d files with a setting or a ruleset in an SQL database.

# If you wish to read settings from a database or any other DBI-compatible
# data source, then this value should be set to the DBI data source name.
#
# This value is required for all of the database functions to work; if it
# is not supplied or is invalid, then all of the database functions will be
# disabled.  See the Perl DBI documentation for all available options.
#
# Example: DB DSN = DBI:DriverName:database=DataBaseName;host=Hostname;port=Port

# This should be a valid SQL statement that returns a single row of data from
# your data source in integer format. This value is periodically checked every
# 15 minutes and if it is numerically greater than the previously retrieved
# value then the MailScanner child will exit and reload its configuration.
#
# This setting is required for all database functions to work; if it is not
# defined or the SQL is invalid then all database functions will be disabled.
#
# Example:  SELECT value FROM config WHERE option='confserialnumber'
SQL Serial Number =

# This should be a valid SQL statement that takes two placeholder arguments
# and returns a single row and column of data.  The first placeholder will
# contain the 'external' variable representation of the MailScanner setting
# being looked-up and the second placeholder will contain the hostname of the
# host that is requesting the data.
#
# This setting is required for all database functions to work; if it is not
# defined or the SQL is invalid then all database functions will be disabled.
#
# Exmaple: SQL Quick Peek = SELECT value FROM config WHERE external = ? AND host = ?
SQL Quick Peek =

# This should be a valid SQL statement that has a single placeholder argument
# and must return two columns and one row per configuration setting.
# The placeholder will contain the hostname of the host requsting the data.
# The first column must return the 'internal' representation of the setting
# and the second column must return the value that should be assigned.
# If the value contains 'foobar.customi[zs]e' then the value is presumed to
# be a database ruleset and will cause the defined 'SQL Ruleset' statement to
# be run and will use 'foobar' as the ruleset name to retrieve the ruleset.
#
# This setting is required for all database functions to work; if it is not
# defined or the SQL is invalid then all database functions will be disabled.
#
# Exmaple: SQL Config = SELECT option, value FROM config WHERE host=?
SQL Config =

# This should be a valid SQL statement that has a single placeholder argument
# and must return two columns and one or more rows.  The first column must be
# a numeric starting at 1 and in ascending order and the second column should
# be the rule string.  The placeholder will contain the ruleset name.
#
# Example: SQL Ruleset = SELECT num, rule FROM ruleset WHERE rulesetname=? ORDER BY num ASC
SQL Ruleset =

# This should be a valid SQL statement that returns a single column and one
# or more rows.  Each row that is returned is pushed into an array and joined
# into a string separated by newlines and then passed into the SpamAssassin API
# using the {post_config_text} attribute. See the SpamAssassin API for details.
# The returned rows should be valid SpamAssassin configuration settings that
# will be processed by SpamAssassin after it has read all of normal configuration.
# Any errors will therefore be reported by SpamAssassin and will show up by
# running 'MailScanner --lint' or 'MailScanner --debug-sa'.
#
# Example:  SQL SpamAssassin Config = SELECT text FROM sa_config

# Advanced Settings

#
# Don't bother changing anything below this unless you really know
# what you are doing, or else if MailScanner has complained about
# your "Minimum Code Status" setting.
#

# When trying to work out the value of configuration parameters which are
# using a ruleset, this controls the behaviour when a rule is checking the
# "To:" addresses.
# If this option is set to "yes", then the following happens when checking
# the ruleset:
#   a) 1 recipient. Same behaviour as normal.
#   b) Several recipients, but all in the same domain (domain.com for example).
#      The rules are checked for one that matches the string "*@domain.com".
#   c) Several recipients, not all in the same domain.
#      The rules are checked for one that matches the string "*@*".
#
# If this option is set to "no", then some rules will use the result they
# get from the first matching rule for any of the recipients of a message,
# so the exact value cannot be predicted for messages with more than 1
# recipient.
#
# This value *cannot* be the filename of a ruleset.
Use Default Rules With Multiple Recipients = no

# When working out from IP address the message was sent from,
# no or 0  ==> use the SMTP client address, ie. the address of the system
#              talking to the MailScanner server. This is the normal setting.
# yes or 1 ==> use the first IP address contained in the first "Received:"
#              header at the top of the email message's headers.
# Any number > 1 ==> use the first IP address contained in the n-th
#                    "Received:" header starting from the top of the email
#                    message's headers.
# Users of BarricadeMX should note that this setting will always be forced
# to 2, so it will always give you IP address of the system connecting to
# BarricadeMX.
#
# This is very useful when you are injecting mail into a MailScanner server
# using "fetchmail" as otherwise all mail will appear to be coming from the
# the IP address of the system running "fetchmail", and not the address the
# mail actually came from.
# You need to use this together with the "invisible" option in "fetchmail",
# so that "fetchmail" does not add its own "Received:" header to the start
# of the message.
#
# This value *cannot* be the filename of a ruleset.
Read IP Address From Received Header = no

# When putting the value of the spam score of a message into the headers,
# how do you want to format it. If you don't know how to use sprintf() or
# printf() in C, please *do not modify* this value. A few examples for you:
# %d     ==> 12
# %5.2f  ==> 12.34
# %05.1f ==> 012.3
# This can also be the filename of a ruleset.

# The numbers are all set in seconds. They are:
# 1. Non-Spam cache lifetime                           = 30 minutes
# 2. Spam (low scoring) cache lifetime                 = 5 minutes
# 3. High-Scoring spam cache lifetime                  = 3 hours
# 4. Viruses cache lifetime                            = 2 days

# When attempting delivery of outgoing messages, should we do it in the
