Hello all,
I have been having some very annoying trouble lately with mailscanner
using spamassassin. As far as I have looked (which is pretty far) I have
correct settings for mailscanner and spamassassin. (spamassassin 2.64
and mailscanner 4.35.11)
The problem is that mailscanner does not appear to be calling
spamassassin properly but is not generating any logs to indicate the
problem. I thought mailscanner was calling spamassassin and it was
returning 0 everytime but it turned out that "Always Include
SpamAssassin Report = yes" was giving every message a score of 0. After
changing this it appears that mailscanner is not running spamassassin at
all. I used strace on mailscanner and sifted though the results but
could not find anything conclusinve. A test of spamassassin from the
command line on a message returns a reasonable result (other than 0) for
a message but mailscanner is not doing this. I have included
Mailscanner.conf and spam.assassin.prefs.conf. Can anyone help? I hope
it is something really simple that I have misssed but I have been
looking at it for so long now that its invisible to me.
thanks.

# Main configuration file for the MailScanner E-Mail Virus Scanner
#
# 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.

# Set the directory containing all the reports in the required language

# RULE: It must not contain any spaces!
# Note: Some Symantec scanners complain (incorrectly) about "."

# about HTML-based attacks. This includes Zip-Password
# so you don't need to include both.
#
# The default of "All-Viruses" means that no senders of viruses will be

#
# Note: Once you have deployed this into "production" use, you should set
# Note: this option to "no" so you don't bombard thousands of people with
# Note: useless messages they don't want!

# This can also be the filename of a ruleset.
Still Deliver Silent Viruses = no
# Strings listed here will be searched for in the output of the virus scanners.
# It works to achieve the opposite effect of the "Silent Viruses" listed above.

# 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 quarantine
# bounce - send a rejection message back to the sender
# forward user at domain.com - forward a copy of the message to user at domain.com
# 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.
#
# This can also be the filename of a ruleset.
#Spam Actions = store forward anonymous at ecs.soton.ac.uk
Spam Actions = deliver
# This is just like the "Spam Actions" option above, except that it applies
# then the score from SpamAssassin is higher than the "High SpamAssassin Score"

# delete - delete the message
# store - store the message in the quarantine
# forward user at domain.com - forward a copy of the message to user at domain.com

# the original message if they think it was not
# spam.
#
# This can also be the filename of a ruleset.
High Scoring Spam Actions = deliver

# There are 3 reports:
# Sender Spam Report - sent when a message triggers both a Spam

Recipient Spam Report = %report-dir%/recipient.spam.report.txt
# You can use this ruleset to enable the "bounce" Spam Action.
# You must *only* enable this for mail from sites with which you have
# agreed to bounce possible spam. Use it on low-scoring spam only (<10)
# and only to your regular customers for use in the rare case that a
# message is mis-tagged as spam when it shouldn't have been.

# This is the syslog "facility" name that MailScanner uses. If you don't
# know what a syslog facility name is, then either don't change this value

#
# If you are using Postfix you may well need to use some of the settings
# below, as the home directory for the "postfix" user cannot be written
# to by the "postfix" user.
# You may also need to use these if you have installed SpamAssassin
# somewhere other than the default location.
#
# The per-user files (bayes, auto-whitelist, user_prefs) are looked
# for here and in ~/.spamassassin/. Note the files are mutable.
# If this is unset then no extra places are searched for.
# If using Postfix, you probably want to set this as shown in the example

# chown postfix.postfix /var/spool/MailScanner/spamassassin
#SpamAssassin User State Dir = /var/spool/MailScanner/spamassassin
SpamAssassin User State Dir = /var/lib/MailScanner
# This setting is useful if SpamAssassin is installed in an unusual place,
# e.g. /opt/MailScanner. The install prefix is used to find some fallback
# directories if neither of the following two settings work.
# If this is set then it adds to the list of places that are searched;
# otherwise it has no effect.
#SpamAssassin Install Prefix = /opt/MailScanner
SpamAssassin Install Prefix = /etc/MailScanner

# prefix/etc/mail/spamassassin, /usr/local/etc/spamassassin, /etc/spamassassin,
# /etc/mail/spamassassin, and maybe others.
# If this is set then it adds to the list of places that are searched;
# otherwise it has no effect.
#SpamAssassin Local Rules Dir = /etc/MailScanner/mail/spamassassin
SpamAssassin Local Rules Dir = /etc/MailScanner/rules
# The default rules are searched for here, and in prefix/share/spamassassin,

#
# 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 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.
Spam Score Number Format = %5.2f
# Set Debug to "yes" to stop it running as a daemon and just process
# one batch of messages and then exit.
Debug = no
# Do you want to debug SpamAssassin from within MailScanner?
Debug SpamAssassin = yes
# Set Run In Foreground to "yes" if you want MailScanner to operate
# normally in foreground (and not as a background daemon).
# Use this if you are controlling the execution of MailScanner
# with a tool like DJB's 'supervise' (see http://cr.yp.to/daemontools.html).
Run In Foreground = no
# If you are using an LDAP server to read the configuration, these

# This option is intended for people who want to log more information
# about messages than what is put in syslog. It is intended to be used
# with a Custom Function which has the side-effect of logging information,
# perhaps to an SQL database, or any other processing you want to do
# after each message is processed.
# Its value is completely ignored, it is purely there to have side
# effects.
# If you want to use it, read CustomConfig.pm.
Always Looked Up Last = no
# When attempting delivery of outgoing messages, should we do it in the
# background or wait for it to complete? The danger of doing it in the
# background is that the machine load goes ever upwards while all the
# slow sendmail processes run to completion. However, running it in the
# foreground may cause the mail server to run too slowly.
Deliver In Background = yes
# Attempt immediate delivery of messages, or just place them in the outgoing
# queue for the MTA to deliver when it wants to?
# batch -- attempt delivery of messages, in batches of up to 20 at once.
# queue -- just place them in the queue and let the MTA find them.
# This can also be the filename of a ruleset. For example, you could use a
# ruleset here so that messages coming to you are immediately delivered,
# while messages going to any other site are just placed in the queue in
# case the remote delivery is very slow.
Delivery Method = queue
# Are you using Exim with split spool directories? If you don't understand
# this, the answer is probably "no". Refer to the Exim documentation for

# Where to put the virus scanning engine lock files.
# These lock files are used between MailScanner and the virus signature
# "autoupdate" scripts, to ensure that they aren't both working at the

Lockfile Dir = /tmp
# Where to put the code for your "Custom Functions". No code in this

# Minimum acceptable code stability status -- if we come across code
# that's not at least as stable as this, we barf.
# This is currently only used to check that you don't end up using untested
# virus scanner support code without realising it.
# Levels used are:
# none - there may not even be any code.
# unsupported - code may be completely untested, a contributed dirty hack,
# anything, really.
# alpha - code is pretty well untested. Don't assume it will work.
# beta - code is tested a bit. It should work.
# supported - code *should* be reliable.
#
# Don't even *think* about setting this to anything other than "beta" or
# "supported" on a system that receives real mail until you have tested it
# yourself and are happy that it is all working as you expect it to.
# Don't set it to anything other than "supported" on a system that could
# ever receive important mail.
#
# READ and UNDERSTAND the above text BEFORE changing this.
