This will help me to filter or block that I have written a cgi which allows to transfer files to and from a server and I think mail services use similar methods. It uses normal http multipart post requests (I think put would also be possible) to submit the files. So you have to block http request (usually port 80 and 443 for encrypted connections) which contain http multipart requests, which contain strings like filename="something" in one of the multipart headers and post request. (Perhaps you should look for a http - proxy allowing to stop those transfers)
