i've managed to get most users to switch and start using "7-Zip"
(http://7-zip.org/) which is an open-source alternative. this let me block
ZIP attachments with no guilt. :) the result is users now create ".7z"
files which are allowed through the gateway.
poof, no problems!
they can still open zips, then can still create zips, and while the UI for
7zip is not as sophisticated as WinZip/WinRAR/WinAce etc. it does the job.
'course i'll revisit the problem should 7-zip become popular and the viri
dudes start using it to compress everything.
