I managed to get it to work with this work around in the meanwhile with this settings below, not ideal
# Expand TNEF attachments using an external program (or a Perl module)?
# This should be "yes" unless the scanner you are using (Sophos, McAfee) has
# the facility built-in. However, if you set it to "no", then the filenames
# within the TNEF attachment will not be checked against the filename rules.
Expand TNEF = no
#Deafult was yes
# Where the "file" command is installed.
# This is used for checking the content type of files, regardless of their
# filename.
# To disable Filetype checking, set this value to blank.
File Command =
#default /usr/bin/file
# The maximum depth to which zip archives, rar archives and Microsoft Office
# documents will be unpacked, to allow for checking filenames and filetypes
# within zip and rar archives and embedded within Office documents.
# Note: This setting does *not* affect virus scanning in archives at all.
# To disable this feature set this to 0.
# A common useful setting is this option = 0, and Allow Password-Protected
# Archives = no. That block password-protected archives but does not do
# any filename/filetype checks on the files within the archive.
# This can also be the filename of a ruleset.
Maximum Archive Depth = 0
#Default 3
# Find zip archives by filename or by file contents?
# Finding them by content is a far more reliable way of finding them, but
# it does mean that you cannot tell your users to avoid zip file checking
# by renaming the file from ".zip" to "_zip" and tricks like that.
# Only set this to no (i.e. check by filename only) if you don't want to
# reliably check the contents of zip files. Note this does not affect
# virus checking, but it will affect all the other checks done on the contents
# of the zip file.
# This can also be the filename of a ruleset.
Find Archives By Content = no
#default yes
# Do you want to unpack Microsoft "OLE" documents, such as *.doc, *.xls
# and *.ppt documents? This will extract any files which have been hidden
# by being embedded in these documents.
# There are one or two minor bugs in the third-party code that does the
# processing of these files, so it can cause MailScanner to hang in very
# rare cases.
# ClamAV has its own OLE unpacking code, so you can safely switch this off
# if you just rely on ClamAV for your virus-scanning. Note that this will,
# however, disabled all filename and filetype checking of embedded files.
# This can also be the filename of a ruleset.
Unpack Microsoft Documents = no
#default yes
