nested .zip containing bad files not being caught

Hey all. I have an issue here. It appears that a nested zip archive is
getting through mailscanner. I have mailscanner configured to look into
archives and to block bad files. Here's the scenario... were receiving
a file called instruction.zip which is getting through our scanning. If
you unzip this file, you get another .zip which if you send it through
*does* get caught by mailscanner, and if you unzip that you get
instruction.pif which *does* get caught as well. I've upgraded to
Archive-Zip module version 1.12 as I know the previous version had a
hole. So, any idea what's going on here? I running MailScanner-4.31.6
and have attached my MailScanner.conf file. Also, I've put 2 examples
of the files up on our ftp server. You can grabe them at:
ftp://ftp.usg.edu/pub/mailscanner/file.zip
ftp://ftp.usg.edu/pub/mailscanner/instruction.zip
Help please!

# 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.

# Multiple servers within one site should use an identical value here

# 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.

# then some messages could be greatly delayed. So treat this option as
# "in emergency only".
Max Normal Queue Size = 5000
# The maximum number of attachments allowed in a message before it is
# considered to be an error. Some email systems, if bouncing a message
# between 2 addresses repeatedly, add information about each bounce as
# an attachment, creating a message with thousands of attachments in just
# a few minutes. This can slow down or even stop MailScanner as it uses

# 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.

# message will be treated as if it were not infected with a "Silent Virus".
# If a message is detected as both a silent virus and a non-forging virus,
# then the ___non-forging status will override the silent status.___
# In simple terms, you should list virus names (or parts of them) that you
# know do *not* forge the From address.
# A good example of this is a document macro virus or a Joke program.
# Another word that can be put in this list is the special keyword
# Zip-Password : inserting this will cause senders to be warned about

# This can also be the filename of a ruleset.
Dangerous Content Scanning = yes
# 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.

Allow IFrame Tags = yes
# 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

# and banning all others.
# This can also be the filename of a ruleset.
Log IFrame Tags = no
# 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.
# Value: yes => Allow these tags to be in the message
# no => Ban messages containing these tags
# disarm => Allow these tags, but stop these tags from working
# Note: Disarming can be defeated, it is not 100% safe!
# This can also be the filename of a ruleset.
Allow Form Tags = yes
# Do you want to allow <Script> tags in email messages? This is a bad idea
# as these are used to exploit vulnerabilities in email applications and

# information.
# Value: yes => Allow these tags to be in the message
# disarm => Allow these tags, but stop these tags from working
# Note: Disarming can be defeated, it is not 100% safe!
# Note: You cannot block messages containing web bugs as their detection
# is very vulnerable to false alarms.
# This can also be the filename of a ruleset.
Allow WebBugs = yes
# Do you want to allow <Object Codebase=...> or <Object Data=...> tags

# it, you can do it.
# Value: yes => Allow these tags to be in the message
# no => Ban messages containing these tags
# disarm => Allow these tags, but stop these tags from working
# 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

# ============ ================= ============================
# no no Blocked
# no yes Blocked
# disarm no Specified HTML tags disarmed
# disarm yes Specified HTML tags disarmed
# yes no Nothing, allowed to pass
# yes yes All HTML tags stripped
#
# If an "Allow ... Tags = yes" is triggered by a message, and this
# "Convert Dangerous HTML To Text" is set to "yes", then the HTML
# message will be converted to plain text. This makes the HTML
# harmless, while still allowing your users to see the text content

# Logging
# -------

# 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
# or else go and read "man syslog.conf". The default value of "mail" will
# cause the MailScanner logs to go into the same place as all your other
# mail logs.
Syslog Facility = mail
# Do you want to log the processing speed for each section of the code
# for a batch? This can be very useful for diagnosing speed problems,
# particularly in spam checking.
Log Speed = no
# Do you want all spam to be logged? Useful if you want to gather
# spam statistics from your logs, but can increase the system load quite
# a bit if you get a lot of spam.
Log Spam = no
# Do you want all non-spam to be logged? Useful if you want to see
# all the SpamAssassin reports of mail that was marked as non-spam.
# Note: It will generate a lot of log traffic.
Log Non Spam = no
# Log all the filenames that are allowed by the Filename Rules, or just
# the filenames that are denied?

# 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

# 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

# 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
# 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?

# If you are using an LDAP server to read the configuration, these
# are the details required for the LDAP connection. The connection

# 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.

# 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.
