I am attaching my dspam.conf, hopefully attachments aren't a pain. I
will remember what you said about patches or, if acceptable, I will
attach them in the future.

If it isn't necessary in most configurations, then maybe an ifdef around
the two versions of the two lines with a define right after the main
comment body at the beginning of the source.

## dspam.conf -- DSPAM configuration file
##

#
# DSPAM Home: Specifies the base directory to be used for DSPAM storage
#
Home /var/dspam

#
# StorageDriver: Specifies the storage driver backend (library) to use.
# You'll only need to set this if you are using dynamic storage driver plugins
# from a binary distribution. The default build statically links the storage
# driver (when only one is specified at configure time), overriding this
# setting, which only comes into play if multiple storage drivers are specified
# at configure time. When using dynamic linking, be sure to include the path 
# to the library if necessary, and some systems may use an extension other 
# than .so (e.g. OSX uses .dylib).
#
# Options include:
#
#   libmysql_drv.so     libpgsql_drv.so   libsqlite_drv.so
#   libsqlite3_drv.so   libhash_drv.so
#
# IMPORTANT: Switching storage drivers requires more than merely changing
# this option. If you do not wish to lose all of your data, you will need to
# migrate it to the new backend before making this change.
#
StorageDriver /usr/local/lib/libhash_drv.so

#
# Trusted Delivery Agent: Specifies the local delivery agent DSPAM should call 
# when delivering mail as a trusted user. Use %u to specify the user DSPAM is 
# processing mail for. It is generally a good idea to allow the MTA to specify 
# the pass-through arguments at run-time, but they may also be specified here.
#
# Most operating system defaults:
#TrustedDeliveryAgent "/usr/bin/procmail"       # Linux
#TrustedDeliveryAgent "/usr/bin/mail"           # Solaris
#TrustedDeliveryAgent "/usr/libexec/mail.local" # FreeBSD
#TrustedDeliveryAgent "/usr/bin/procmail"       # Cygwin
#
# Other popular configurations:
#TrustedDeliveryAgent "/usr/cyrus/bin/deliver"	# Cyrus
#TrustedDeliveryAgent "/bin/maildrop"		# Maildrop
#TrustedDeliveryAgent "/usr/local/sbin/exim -oMr spam-scanned" # Exim
#
#TrustedDeliveryAgent "/usr/bin/procmail"
#TrustedDeliveryAgent "/usr/sbin/sendmail"

#
# Untrusted Delivery Agent: Specifies the local delivery agent and arguments
# DSPAM should use when delivering mail and running in untrusted user mode.
# Because DSPAM will not allow pass-through arguments to be specified to 
# untrusted users, all arguments should be specified here. Use %u to specify
# the user DSPAM is processing mail for. This configuration parameter is only 
# necessary if you plan on allowing untrusted processing.
#
#UntrustedDeliveryAgent "/usr/bin/procmail -d %u"

#
# SMTP or LMTP Delivery: Alternatively, you may wish to use SMTP or LMTP 
# delivery to deliver your message to the mail server instead of using a
# delivery agent. You will need to configure with --enable-daemon to use host 
# delivery, however you do not need to operate in daemon mode. Specify an IP 
# address or UNIX path to a domain socket below as a host.
#
# If you would like to set up DeliveryHost's on a per-domain basis, use
# the syntax: DeliveryHost.domain.com 1.2.3.4
#
DeliveryHost        127.0.0.1
DeliveryPort        10026
DeliveryIdent       localhost
DeliveryProto       SMTP

#
# FallbackDomains: If you want to specify certain domains as fallback domains,
# enable this option. For example, you could create a user @domain.com, and
# if bob at domain.com does not resolve to a known user on the system, the user
# could default to your @domain.com user. NOTE: This also requires designating
# fallbackDomain for the domain name; 
# e.g. dspam_admin ch pref domain.com fallbackDomain on 
#
#FallbackDomains on

#
# Quarantine Agent: DSPAM's default behavior is to quarantine all mail it 
# thinks is spam. If you wish to override this behavior, you may specify
# a quarantine agent which will be called with all messages DSPAM thinks is
# spam. Use %u to specify the user DSPAM is processing mail for.
#
#QuarantineAgent	"/usr/bin/procmail -d spam"

#
# DSPAM can optionally process "plused users" (addresses in the user+detail
# form) by truncating the username just before the "+", so all internal
# processing occurs for "user", but delivery will be performed for
# "user+detail". This is only useful if the LDA can handle "plused users"
# (for example Cyrus IMAP) and when configured for LMTP delivery above
#
# NOTE: Plused detail presently only works when usernames are provided and
#       not fully qualified email address (@domain).
#
#EnablePlusedDetail	on

#
# Quarantine Mailbox: DSPAM's LMTP code can send spam mail using LMTP to a 
# "plused" mailbox (such as user+quarantine) leaving quarantine processing
# for retraining or deletion to be performed by the LDA and the mail client.
# "plused" mailboxes are supported by Cyrus IMAP and possibly other LDAs.
# The mailbox name must have the +
#
#QuarantineMailbox	+quarantine

#
# OnFail: What to do if local delivery or quarantine should fail. If set
# to "unlearn", DSPAM will unlearn the message prior to exiting with an
# un successful return code. The default option, "error" will not unlearn
# the message but return the appropriate error code. The unlearn option
# is use-ful on some systems where local delivery failures will cause the
# message to be requeued for delivery, and could result in the message
# being processed multiple times. During a very large failure, however, 
# this could cause a significant load increase.
#
OnFail error

#
# Trusted Users: Only the users specified below will be allowed to perform
# administrative functions in DSPAM such as setting the active user and
# accessing tools. All other users attempting to run DSPAM will be restricted;
# their uids will be forced to match the active username and they will not be
# able to specify delivery agent privileges or use tools.
#
Trust root
Trust mail
Trust postfix
#Trust nobody
#Trust majordomo

#
# Debugging: Enables debugging for some or all users. IMPORTANT: DSPAM must
# be compiled with debug support in order to use this option. DSPAM should
# never be running in production with debug active unless you are 
# troubleshooting problems.
#
# DebugOpt: One or more of: process, classify, spam, fp, inoculation, corpus
#   process     standard message processing
#   classify    message classification using --classify
#   spam        error correction of missed spam
#   fp          error correction of false positives
#   inoculation message inoculations (source=inoculation)
#   corpus      corpusfed messages (source=corpus)

# ClassAlias: Alias a particular class to spam/nonspam. This is useful if
# classifying things other than spam.

#
# Training Mode: The default training mode to use for all operations, when
# one has not been specified on the commandline or in the user's preferences.
# Acceptable values are: 
#     toe     Train on Error (Only)
#     teft    Train Everything (Trains on every message)

# TestConditionalTraining: By default, dspam will retrain certain errors
# until the condition is no longer met. This usually accelerates learning.
# Some people argue that this can increase the risk of errors, however.

# on the commandline. See the documentation for a list of available features.
# If _any_ features are specified on the commandline, these are ignored.
#
#Feature noise
Feature whitelist

# Training Buffer: The training buffer waters down statistics during training.
# It is designed to prevent false positives, but can also dramatically reduce
# dspam's catch rate during initial training. This can be a number from 0
# (no buffering) to 10 (maximum buffering). If you are paranoid about false
# positives, you should probably enable this option.

#    graham      Graham-Bayesian ("A Plan for Spam")
#    burton      Burton-Bayesian (SpamProbe)
#    robinson    Robinson's Geometric Mean Test (Obsolete)
#    chi-square  Fisher-Robinson's Chi-Square Algorithm
#
# You may have multiple algorithms active simultaneously, but it is strongly
# recommended that you group Bayesian algorithms with other Bayesian
# algorithms, and any use of Chi-Square remain exclusive.
#
# NOTE: For standard "CRM114" Markovian weighting, use 'naive', or consider

#
# Tokenizer: Specify the tokenizer to use. The tokenizer is the piece
# responsible for parsing the message into individual tokens. Depending on
# how many resources you are willing to trade off vs. accuracy, you may
# choose to use a less or more detailed tokenizer:
#   word    uniGram (single word) tokenizer
#           Tokenizes message into single individual words/tokens
#           example: "free" and "viagra"
#   chain   biGram (chained tokens) tokenizer (default)
#           Single words + chains adjacent tokens together
#           example: "free" and "viagra" and "free viagra"
#   sbph    Sparse Binary Polynomial Hashing tokenizer
#           Creates sparse token patterns across sliding window of 5-tokens
#           example: "the quick * fox jumped" and "the * * fox jumped"
#   osb     Orthogonal Sparse biGram
#           Similar to SBPH, but only uses the biGrams
#           example: "the * * fox" and "the * * * jumped"

#
# HashPctIncrease: Increase the next extent size by n% from the size of the

# HashExtentSize can be too small for certain high-volume users, and can also
# help keep seeks nice and speedy and/or prevent too many unnecessary extents 
# from being created when using a low HashMaxSeek. The default behavior, when

HashPctIncrease 10

#
# HashMaxSeek: The maximum number of record seeks when inserting a new record
# before failing or adding a new extent. This ultimately translates into the
# max # of acceptable seeks per segment. Setting this too high will exhaustively

# as even older extents will continue to fill as training progresses.

# -- LDAP --

#
# LDAP: Perform various LDAP functions depending on LDAPMode variable.

# -- Profiles --

#
# You can specify multiple storage profiles, and specify the server to
# use on the commandline with --profile. For example:
#
#Profile DECAlpha
#MySQLServer.DECAlpha   10.0.0.1
#MySQLPort.DECAlpha     3306
#MySQLUser.DECAlpha     dspam
#MySQLPass.DECAlpha     changeme
#MySQLDb.DECAlpha       dspam
#MySQLCompress.DECAlpha true
#
#Profile Sun420R
#MySQLServer.Sun420R    10.0.0.2
#MySQLPort.Sun420R      3306
#MySQLUser.Sun420R      dspam
#MySQLPass.Sun420R      changeme
#MySQLDb.Sun420R        dspam
#MySQLCompress.Sun420R  false
#
#DefaultProfile DECAlpha

#
# If you're using storage profiles, you can set failovers for each profile.
# Of course, if you'll be failing over to another database, that database
# must have the same information as the first. If you're using a global
# database with no training, this should be relatively simple. If you're
# configuring per-user data, however, you'll need to set up some type of
# replication between databases.
#
#Failover.DECAlpha      SUN420R
#Failover.Sun420R       DECAlpha

# If the storage fails, the agent will follow each profile's failover up to
# a maximum number of failover attempts. This should be set to a maximum of
# the number of profiles you have, otherwise the agent could loop and try
# the same profile multiple times (unless this is your desired behavior).
#
#FailoverAttempts       1

#
# Ignored headers: If DSPAM is behind other tools which may add a header to
# incoming emails, it may be beneficial to ignore these headers - especially
# if they are coming from another spam filter. If you are _not_ using one of
# these tools, however, leaving the appropriate headers commented out will
# allow DSPAM to use them as telltale signs of forged email.

# Lookup: Perform lookups on streamlined blackhole list servers (see
# http://www.nuclearelephant.com/projects/sbl/). The streamlined blacklist
# server is machine-automated, unsupervised blacklisting system designed to
# provide real-time and highly accurate blacklisting based on network spread.
# When performing a lookup, DSPAM will automatically learn the inbound message 
# as spam if the source IP is listed. Until an official public RABL server is 
# available, this feature is only useful if you are running your own 
# streamlined blackhole list server for internal reporting among multiple mail 
# servers. Provide the name of the lookup zone below to use.
#
# This function performs standard reverse-octet.domain lookups, and while it

#
# ParseToHeaders: In lieu of setting up individual aliases for each user,
# DSPAM can be configured to automatically parse the To: address for spam and
# false positive forwards. From there, it can be configured to either set the
# DSPAM user based on the username specified in the header and/or change the
# training class and source accordingly. The options below can be used to 
# customize most common types of header parsing behavior to avoid the need for
# multiple aliases, or if using LMTP, aliases entirely..
#
# ParseToHeader: Parse the To: headers of an incoming message. This must be
#                set to 'on' to use either of the following features.
# 
# ChangeModeOnParse: Automatically change the class (to spam or innocent)
#   depending on whether spam- or notspam- was specified, and change the source
#   to 'error'. This is convenient if you're not using aliases at all, but
#   are delivering via LMTP.
#
# ChangeUserOnParse: Automatically change the username to match that specified
#   in the To: header. For example, spam-bob at domain.tld will set the username
#   to bob, ignoring any --user passed in. This may not always be desirable if
#   you are using virtual email addresses as usernames. Options:

# necessary. In these cases you can activate certain features in DSPAM to
# compensate. 'returnCodes' causes DSPAM to return an exit code of 99 if
# the message is spam, 0 if not, or a negative code if an error has occured.
# Specifying 'case' causes DSPAM to force the input usernames to lowercase.
# Spceifying 'lineStripping' causes DSPAM to strip ^M's from messages passed
# in.
#
#Broken returnCodes
#Broken case
#Broken lineStripping

#
# MaxMessageSize: You may specify a maximum message size for DSPAM to process.
# If the message is larger than the maximum size, it will be delivered 
# without processing. Value is in bytes.
#
#MaxMessageSize 4194304

#
# Virus Checking: If you are running clamd, DSPAM can perform stream-based
# virus checking using TCP. Uncomment the values below to enable virus
# checking. 
#
# ClamAVResponse: reject (reject or drop the message with a permanent failure)
#                 accept (accept the message and quietly drop the message)
#                 spam   (treat as spam and quarantine/tag/whatever)

#ClamAVHost	127.0.0.1

# -- CLIENT / SERVER --

#
# Daemonized Server: If you are running DSPAM as a daemonized server using
# --daemon, the following parameters will override the default. Use the
# ServerPass option to set up accounts for each client machine. The DSPAM
# server will process and deliver the message based on the parameters 
# specified. If you want the client machine to perform delivery, use
# the --stdout option in conjunction with a local setup.

ServerPID              /var/dspam/dspam.pid

#
# ServerMode specifies the type of LMTP server to start. This can be one of:
#     dspam: DSPAM-proprietary DLMTP server, for communicating with dspamc
#  standard: Standard LMTP server, for communicating with Postfix or other MTA
#      auto: Speak both DLMTP and LMTP; auto-detect by ServerPass.IDENT
#
ServerMode auto 

# If supporting DLMTP (dspam) mode, dspam clients will require authentication 
# as they will be passing in parameters. The idents below will be used to
# determine which clients will be speaking DLMTP, so if you will be using
# both LMTP and DLMTP from the same host, be sure to use something other
# than the server's hostname below (which will be sent by the MTA during a 
# standard LMTP LHLO).
# 
#ServerPass.Relay1	"secret"
#ServerPass.Relay2	"password"

# If supporting standard LMTP mode, server parameters will need to be specified
# here, as they will not be passed in by the mail server. The ServerIdent
# specifies the 250 response code ident sent back to connecting clients and
# should be set to the hostname of your server, or an alias.
#
# NOTE: If you specify --user in ServerParameters, the RCPT TO will be
#       used only for delivery, and not set as the active user for processing.
#
#ServerParameters	"--deliver=innocent -d %u"
ServerParameters	"--deliver=innocent,spam"
ServerIdent		"SOMETHING.localdomain"

# If you wish to use a local domain socket instead of a TCP socket, uncomment
# the following. It is strongly recommended you use local domain sockets if
# you are running the client and server on the same machine, as it eliminates
# much of the bandwidth overhead.
#
ServerDomainSocketPath  "/tmp/dspam.sock"

#
# Client Mode: If you are running DSPAM in client/server mode, uncomment and
# set these variables. A ClientHost beginning with a / will be treated as
# a domain socket.

#ClientHost	/tmp/dspam.sock
#ClientIdent	"secret at Relay1"

# RABLQueue: Touch files in the RABL queue
# If you are a reporting streamlined blackhole list participant, you can
# touch ip addresses within the directory the rabl_client process is watching.
#
#RABLQueue	/var/spool/rabl

# DataSource: If you are using any type of data source that does not include
# email-like headers (such as documents), uncomment the line below. This
# will cause the entire input to be treated like a message "body"
#
#DataSource      document

# ProcessorWordFrequency: By default, words are only counted once per message.
# If you are classifying large documents, however, you may wish to count once
# per occurrence instead.
#
#ProcessorWordFrequency  occurrence

# ProcessorURLContext: By default, a URL context is generated for URLs, which
# records their tokens as separate from words found in documents. To use
# URL tokens in the same context as words, turn this feature off. 
#
ProcessorURLContext on

# ProcessorBias: Bias causes the filter to lean more toward 'innocent', and
# usually greatly reduces false positives. It is the default behavior of
# most Bayesian filters (including dspam). 
#
# NOTE: You probably DONT want this if you're using Markovian Weighting, unless
# you are paranoid about false positives.
