You don't need to hack the software to get that working. I have exactly
that setup over here and I did not hacked anything to get mailman to process
the mail.
Before I start giving you advices... Can you please post some more info
how you have chained everything together? The stuff from master.cf is
important, then main.cf (how do you identify mailman domains), then your
mm_cfg.py, then your dspam.conf and last the output of "dspam --version".
first my master.cf:
127.0.0.1:10026 inet n - - - - smtpd
-o content_filter=
-o
receive_override_options=no_unknown_recipient_checks,no_header_body_checks
-o smtpd_helo_restrictions=
-o smtpd_client_restrictions=
-o smtpd_sender_restrictions=
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o mynetworks=127.0.0.0/8
-o smtpd_authorized_xforward_hosts=127.0.0.0/8
smtp inet n - n - - smtpd
-o content_filter=lmtp:inet:127.0.0.1:2424
mailman unix - n n - - pipe flags=FR user=mailman
argv=/usr/lib/mailman/bin/postfix-to-mailman.py \${nexthop} ${user}
the first entry is for giving back mail to postfix after checking.
the second line lets postfix give mails to lda which is in my case dspam.
(dspam is listening on port 2424 in LMTP mode)
The third is the mailman transport, which is supposed to collect... that was
something i tried out, but it failed (i got several python errors).
so i tried the following:
(excerpt of my main.cf)
....
alias_maps = hash:/var/lib/mailman/data/aliases
....
mydestination = $myhostname, localhost, localhost.localdomain, lists.mydom.ain
....
that finally worked sofar, if i let dspam give back the mails to postfix.
in the alias map, there will be the pipe mapping to the mailman scripts.
In my dspam.conf i have the following (and the whole dspam.conf as attachment):
....
TrustedDeliveryAgent "/usr/libexec/dovecot/deliver -d %u"
....
QuarantineAgent "/usr/libexec/dovecot/deliver -d %u -m SPAM"
DeliveryHost.lists.mydom.ain 127.0.0.1
DeliveryPort 10026
DeliveryIdent localhost
DeliveryProto SMTP
...
ServerPort 2424
...
ServerPID /var/run/dspam/dspam.pid
ServerMode standard
at last... my mm_cfg.py:
MTA = 'Postfix'
DEFAULT_EMAIL_HOST = 'lists.mydom.ain'
DEFAULT_URL_HOST = 'mydom.ain'
DEFAULT_URL_PATTERN = 'https://ssl.%s/services/mailman/'
add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)
IMAGE_LOGOS = '/services/mailman/mailman-icons/'
POSTFIX_STYLE_VIRTUAL_DOMAINS = [DEFAULT_EMAIL_HOST]
PUBLIC_ARCHIVE_URL = 'https://ssl.%s/services/mailman/pipermail/%(listname)s'
---
There was a tutorial, that includes the virtual-mailman transport table, which
maps my subdomain to the local map. That points to the mailman scripts... so
this is probably also obsolete now.
the last information requested: my mailman version:

that is mail-filter/dspam-3.8.0-r15 from gentoo repository
As you can see, i've tried out several things and haven't found my
favorite solution yet. The base configuration (without mailman) is from
http://www.howtoforge.org/postfix_mysql_dovecot_dspam_clamav_postgrey_rbl_debian_etch
all on one single box. Now i try to include mailman.
at this moment right now, mailman gets mails and processes them. Personal
Mail will not be delivered because dspam doesn't find a delivery host for
all other mails.
a lot of information, hope that helps.
Sincerly

## dspam.conf -- DSPAM configuration file
##
#
# DSPAM Home: Specifies the base directory to be used for DSPAM storage
#
Home /var/spool/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/lib/dspam/libmysql_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/libexec/dovecot/deliver -d %u"
#
# 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 24
#DeliveryIdent localhost
#DeliveryProto LMTP
DeliveryHost.lists.mydom.ain 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 [email protected] 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"
QuarantineAgent "/usr/libexec/dovecot/deliver -d %u -m 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
#
#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.

# 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

# 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)
# tum Train Until Mature (Train only tokens without enough data)
# notrain Do not train or store signatures (large ISP systems, post-train)

# 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

# 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"

# -- Profiles --

#
#Profile DECAlpha
#MySQLServer.DECAlpha 10.0.0.1
#MySQLPort.DECAlpha 3306
#MySQLUser.DECAlpha dspam
#MySQLPass.DECAlpha changeme
#MySQLDb.DECAlpha dspam
#MySQLCompress.DECAlpha true
#MySQLReconnect.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
#MySQLReconnect.Sun420R true
#
#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

# TrainPristine: for systems where the original message remains server side
# and can therefore be presented in pristine format for retraining. This option
# will cause DSPAM to cease all writing of signatures and DSPAM headers to the
# message, and deliver the message in as pristine format as possible. This mode
# REQUIRES that the original message in its pristine format (as of delivery)
# be presented for retraining, as in the case of webmail, imap, or other
# applications where the message is actually kept server-side during reading,
# and is preserved. DO NOT use this switch unless the original message can be
# presented for retraining with the ORIGINAL HEADERS and NO MODIFICATIONS.
#
# NOTE: You can't use this setting with dspam_trian; if you're going to use it,
# wait until after you train any corpora.

#
# Opt: in or out; determines DSPAM's default filtering behavior. If this value
# is set to in, users must opt-in to filtering by dropping a .dspam file in
# /var/dspam/opt-in/user.dspam (or if you have homedirs configured, a .dspam
# folder in their home directory). The default is opt-out, which means all
# users will be filtered unless a .nodspam file is dropped in
# /var/dspam/opt-out/user.nodspam
#

#
# TrackSources: specify which (if any) source addresses to track and report
# them to syslog (mail.info). This is useful if you're running a firewall or
# blacklist and would like to use this information. Spam reporting also drops
# RABL blacklist files (see http://www.nuclearelephant.com/projects/rabl/).
#
#TrackSources spam nonspam
#
# 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, [email protected] 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:
# on or user take the portion before the @ sign only
# full take everything after the initial {spam,notspam}-.

# Broken MTA Options: Some MTAs don't support the proper functionality
# 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.

#
# Virus Checking: If you are running clamd, DSPAM can perform stream-based
# virus checking using TCP. Uncomment the values below to enable virus

# 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 standard
# 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.

#ServerDomainSocketPath "/var/run/dspam/dspam.sock"

# Client Mode: If you are running DSPAM in client/server mode, uncomment and
