Does this policy apply to zip-files only? How is the status of prohibited content(-type) determined? If it just by file extension then I still think this a bit dubious. It seems to be OK to attach .lyx files and images now. But if it is from someone with malicious intent then this a minor stop gap for them since all of these could also contain anything. Just change the file extension. In any way the above gets some documentation of expected behavior out there. If there are further restrictions concerning attachment types it would be perfectly fine just listing the allowed types: lyx-files, images and plaintext (e.g. log files) (and whatever else is allowed and welcome). Since the first line of the new paragraph already mentions zip-files just as an example it might suffice to add something like: "As .zip-files and several other file-types can contain anything, they are prohibited by default and thus you get the error message above." ? greetings Mike
