[Mailman-Users] Virus detection and filtering.

I just discovered that one of our lists was used to distribute a worm
called Win32/Ska.A (A.K.A. Happy99.exe).  This got me thinking, has
anyone plugged in any type of virus detection software into the 
pipe to their server to try and stop such files being distributed
via your lists?

                                       The List Server Admin
                                       list.admin@unh.edu
