I did a fresh centos5.5 installion with the latest Mailscanner and its working perfect, It blocks all zipped exe's as desired. I guess there is some custom configuration on my production servers due to which it fails to work. Will check that out today. <br>

The File Command in my conf was /usr/bin/file , which I then set to /usr/bin/file -i ..

The other protection functions should ignore this setting. It would be pretty useless to only block executables lower than a certain file size and there is no mention in the rules files. (Although most virus executables are extremely small so they can be send in large volumes.)<br>
<br>@Ryan: <br>What is your value of the "File Command" setting? There was a discussion a while ago that this should be set to /path/to/file -i and was set to /path/to/file in older versions of MailScanner.<div>

Is the setting "Max Spam Check Size" maybe excluding your large exe-inside-zip to be slipping through the fishing net?<br>
