We use software that bans attachments not only based upon the file
extensions, but also the file extension of the file within a zip or other
archive file. Therefore, we can allow zip files but still ban zip files
which contain executables or other potentially malicious file types.

Subject: [ExchangeList] file filtering best practice?
In dealing with zip files specifically, I'm wondering what is considered the
"best practice"? We simply remove the file at our edge proxy, but have been
getting a little flack from a few users. Our data shows that nearly 94% of
the .zip files that come in via email are infected so I'm not likely to be
convinced to allow them through.
What say you?
