Default list of blocked extensions
The same applies for the variable dansguardian/groups/.*/banned/mimetypes: By default a fairly obscure list of multimedia MIME extensions is blocked: audio/mpeg audio/x-mpeg audio/x-pn-realaudio audio/x-wav video/mpeg video/x-mpeg2 video/acorn-replay video/quicktime video/x-msvideo video/msvideo application/gzip application/x-gzip application/zip application/compress application/x-compress application/java-vm Multimedia files should be blocked by default (and the list is totally ancient!) and MIME types for executable files are not present. Feedback from a customer from a technical training who tried to use the content scanning in the company confirms that: Using the web is unusable with the default configuration since far too many (harmless) files and extensions are blocked. Unfortunately the list can only be relaxed by editing the UCR templates. I suppose this is also the reason for the performance problems mentioned in Bug 27777 *** Bug 37340 has been marked as a duplicate of this bug. *** *** Bug 37329 has been marked as a duplicate of this bug. *** This issue has been filed against UCS 3. UCS 3 is out of the normal maintenance and many UCS components have vastly changed in UCS 4. If this issue is still valid, please change the version to a newer UCS version otherwise this issue will be automatically closed in the next weeks. This issue has been filed against UCS 3.1.
