Mark, 

You can do this by setting up rules.
The easiest way to set up rules is to open a text doc and set up a rule like 
the one attached to this message.
If you open up this attachment you'll see that after the : is the word NUL. 
Basically this deletes anything it finds with a .exe, .vbs, .scr, or a .hta file 
extension.
There are 2 lines for each file extension. You can add or remove any file 
extension using this code.
Just place this file in the root of each mail host that u want to protect.
I got this file directly from IPSwitch support and it seems to work rather well.

Subject: [imail] Attachment Filters?


Hi all,

In addition to an anti-virus program, is there any way for the server to
selectively filter out attachments based on file types (i.e. file
extensions)?  Since a lot of the email viruses are embedded in .bat or
script files, filtering at the server level might reduce our chances on
getting those viruses.

Some of our users are not very careful in inspecting sender and attachments
before reading emails.  Any comments on this idea will be appreciated.

Let me know if I am totally on the wrong track.

Mark
