Is mimedefang the de facto method for blocking Word macro files? I haven't ever implemented it. Can it work with postfix/amavis? The second thread involving stripping attachments with macros is probably not what we want. What is the generally accepted policy of other organizations? Has there been any progress on using Archive::Zip to add points to Word macro docs? Are there any other approaches to consider for doing this? Thanks, Alex
