Julian,
4.24-5, spamassassin 2.60 in use (plus razor). I've just noticed
that my non-spam email gets no spam report/spam score/lines of ssss's.
This must have changed since my upgrade from 4.23-11. Stuff above my
spam threshold of 5 gets the detailed report:
X-Colby-MailScanner-SpamCheck: spam, SpamAssassin (score=7.724, required 5,
BAYES_99 5.40, HTML_60_70 0.11, HTML_IMAGE_ONLY_02 1.23,
HTML_MESSAGE 0.10, MIME_HTML_NO_CHARSET 0.56, MIME_HTML_ONLY 0.32)
X-Colby-MailScanner-SpamScore: 7
^^^^^^
Where's the fractional portion?
but stuff below my threshold gets zilch in the mail headers, except for
the "found to be clean". This is not what I want (or expect from my settings,
see attached). I would like the detailed SpamAssassin stuff for messages above
the threshold (like above), but just a single line like:
X-Colby-MailScanner-SpamScore: 3.680
for message below the threshold. Misconfiguration on my part, or logic
bug?

# 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.

# How many MailScanner processes do you want to run at a time?
# There is no point increasing this figure if your MailScanner server
# is happily keeping up with your mail traffic.
# If you are running on a server with more than 1 CPU, or you have a
# high mail load (and/or slow DNS lookups) then you should see better
# performance if you increase this figure.
# If you are running on a small system with limited RAM, you should
# note that each child takes just over 20MB.

# As a rough guide, try 5 children per CPU. But read the notes above.

# 2) No attempt at true disinfection will take place
# (but it will still be "cleaned" by removing the nasty attachments

# 3) The recipient will not receive the message,

# All-Viruses : inserting this will stop senders being warned about
# any virus, while still allowing you to warn senders
# about HTML-based attacks.
#
# The default of "All-Viruses" means that no senders of viruses will be

# still be notified.
#
# This can also be the filename of a ruleset.
Silent Viruses = HTML-Form HTML-IFrame All-Viruses
# Still deliver (after cleaning) messages that contained viruses listed
# in the above option ("Silent Viruses") to the recipient?
# Setting this to "yes" is good because it shows management that MailScanner
# is protecting them, but it is bad because they have to filter/delete all
# the incoming virus warnings.
# This can also be the filename of a ruleset.
Still Deliver Silent Viruses = no
# Should encrypted messages be blocked?
# This is useful if you are wary about your users sending encrypted
# messages to your competition.
# This can be a ruleset so you can block encrypted message to certain domains.
Block Encrypted Messages = no
# Should unencrypted messages be blocked?
# This could be used to ensure all your users send messages outside your
# company encrypted to avoid snooping of mail to your business partners.
# This can be a ruleset so you can just check mail to certain users/domains.
Block Unencrypted Messages = no
#
# Options specific to Sophos Anti-Virus
# -------------------------------------
#
# Anything on the next line that appears in brackets at the end of a line
# of output from Sophos will cause the error/infection to be ignored.
# Use of this option is dangerous, and should only be used if you are having
# trouble with lots of corrupt PDF files, for example.
# If you need to specify more than 1 string to find in the error message,
# then put each string in quotes and separate them with a comma.
# For example:
#Allowed Sophos Error Messages = "corrupt", "format not supported"
Allowed Sophos Error Messages =
# The directory (or a link to it) containing all the Sophos *.ide files.
# This is only used by the "sophossavi" virus scanner, and is irrelevant
# for all other scanners.
Sophos IDE Dir = /opt/sophos/ide
# The directory (or a link to it) containing all the Sophos *.so libraries.
# This is only used by the "sophossavi" virus scanner, and is irrelevant

# Removing/Logging dangerous or potentially offensive content
# -----------------------------------------------------------
#
# Do you want to allow partial messages, which only contain a fraction of
# the attachments, not the whole thing? There is absolutely no way to
# scan these "partial messages" properly for viruses, as MailScanner never
# sees all of the attachment at the same time. Enabling this option can
# allow viruses through. You have been warned.
# This can also be the filename of a ruleset so you can, for example, allow
# them in outgoing mail but not in incoming mail.
Allow Partial Messages = no
# Do you want to allow messages whose body is stored somewhere else on the
# internet, which is downloaded separately by the user's email package?
# There is no way to guarantee that the file fetched by the user's email
# package is free from viruses, as MailScanner never sees it.
# This feature is dangerous as it can allow viruses to be fetched from
# other Internet sites by a user's email package. The user would just
# think it was a normal email attachment and would have been scanned by
# MailScanner.
# It is only currently supported by Netscape 6 anyway, and the only people
# who it are the IETF. So I would strongly advise leaving this switched off.
# This can also be the filename of a ruleset.
Allow External Message Bodies = no
# Do you want to allow <IFrame> tags in email messages? This is not a good
# idea as it allows various Microsoft Outlook security vulnerabilities to
# remain unprotected, but if you have a load of mailing lists sending them,
# then you will want to allow them to keep your users happy.
# This can also be the filename of a ruleset, so you can allow them from
# known mailing lists but ban them from everywhere else.
Allow IFrame Tags = no
# Banning <IFrame> tags completely is likely to break some common HTML
# mailing lists, such as Dilbert and other important things like that.
# So before you implement any restriction on them, you can log the sender
# of any message containing an <IFrame>, so that you can set the option
# above to be a ruleset allowing IFrame tags from named "From" addresses
# and banning all others.
# This can also be the filename of a ruleset.
Log IFrame Tags = yes
# Do you want to allow <Form> tags in email messages? This is a bad idea
# as these are used as scams to pursuade people to part with credit card
# information and other personal data.
# This can also be the filename of a ruleset.
Allow Form Tags = no
# Do you want to allow <Object Codebase=...> tags in email messages?
# This is a bad idea as it leaves you unprotected against various
# Microsoft-specific security vulnerabilities. But if your users demand
# it, you can do it.
# This can also be the filename of a ruleset, so you can allow them just
# for specific users or domains.
Allow Object Codebase Tags = no
# Do you want to convert HTML messages containing <IFrame> or
# <Object Codebase=...> tags into plain text?
# This will only apply if you are also allowing the tags to be present
# using the configuration options above. You can allow messages
# that contain the tags, but convert them to plain text. This makes
# the HTML harmless, while still allowing your users to see the text
# content of the messages.
# This can also be the filename of a ruleset, so you can make this apply
# only to specific users or domains.
Convert Dangerous HTML To Text = no
# Do you want to convert all HTML messages into plain text?
# This is very useful for users who are children or are easily offended

# 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

# message to reach the original recipient.
# attachment - Convert the original message into an attachment
# of the message. This means the user has to take
