Dale,
I considered notifying clients when a virus was blocked but after talking
with several of my clients, the general consensus was that they appreciate
that they are being blocked, but don't want to be interrupted with an email
each time one is blocked. In fact, I had so many tell me that they don't
want to get notices, that I implemented a server-wide policy that all
quarantined items (viruses) will be automatically deleted rather than saved
for any period of time (unless someone really wants to keep them for some
strange reason <grin>). This way if a virus storms hit, the server does what
it should do... remove them quietly and efficiently so the clients (and
myself) can continue working. </2cents>
