gfi virus/exploits test

[Robin M.]

Hi GFI has a virus exploits page which tests the security of your email
scanning software.
http://www.gfi.com/emailsecuritytest/
Some of the tests are not caught by mailscanner. Specifically it seems
that attachments without filnames are able to make it past. This means
that vb scripts can make it past mailscanner.
I have tested anomy and was able to prevent this by forcing all files to
have a default name and then in turn deleting all files which had the
default name.
Is there any way to configure mailscanner to do the same, or is it
possible to use anomy with mailscanner ?
