I'm not sure how the scanner will open up a password protected document to scan it if it doesn't have the password. I would be the same thing with password protected zips.
The best approach with MS docs in my opinion is to block all the old office formats (.xls, .doc ....) since back then MS didn't make a distinction between macro and non-macro enabled file formats and then block all new macro enabled office docs such as .xlsm, .docm etc etc. -- Hermes Secure Email Gateway Hermes Secure Email Gateway combines Open Source technologies such as Postfix, Apache SpamAssassin, ClamAV, Amavisd-new, MySQL and CipherMail under one unified web based Web GUI for easy administration and management of your incoming and ougoing email for your organization.
