To accomodate Word 2007, add the following lines to your filename.rule.conf file being very careful to use "tabs" instead of "spaces" between the fields in each line that is not commented out. Alswo you may have different ideas about which file types to allow or deny so you should review carefully before implementing.


# Word 2007 File Type Extensions
# -------------------------------------------
allow \.docx$ Word 2007 XML Document      Word 2007 XML Document
deny \.docmx$ Word 2007 XML Macro-Enabled Document      Word 2007 XML Macro-Enabled Document

# ----------- End Insert

You probably also want to change or delete the defaults for the "repetitive filename extensions", like the ones below, to accommodate the tendency of the Office programs to add some new attachment with aaaaa.xxx.yyy filenames.

     # Repeated file extension, e.g. blah.zip.zip
     allow   (\.[a-z0-9]{3})\1$      -       -

     # Other double file extensions. This catches any hidden filenames.
     deny    \.[a-z][a-z0-9]{2,3}\s*\.[a-z0-9]{3}$   Found possible filename hiding  Attempt to hide real filename extension

Best regards,

Steve

Thanks Steve, I'll add these for office 2007. The problem I am having is with office XP and 2003 files however.
It affects both outgoing and incoming e-mails.
(We're not using 2007 because of the $$$ involved with upgrading and there's a good chance it'll become openoffice :-))
