On one of my mail servers, it is able to peek into a zip and look for  
file types. So I set it to block exe, bat, etc. Otherwise, zip is fine.

Perhaps this would be an easy addition to ASSP. I'll see if I can  
write a small perl script to do this.

Fritz, if i write it in bash, can that be called within the ASSP  
scanning process?

I feel this approach, whether bash or perl is better than letting it  
get as far as hitting CLAM, which is my last line as it is too  
resource heavy.

In 5+ years I had 2 false positives on my old server with this "look  
into a zip" method. Both times they were zipped zip files, and the  
developer patched them quickly. It's something worth looking into.
