In some organisations it might make sense to notify *in-house* senders 
of viruses, which can be done with a ruleset on Notify Senders and/or on 
Notify Senders of Viruses.

Likewise, Julian has provided options for notifying of various types of 
bad content separately from viruses:

Notify Senders = %rules-dir%/notify.senders.rules
Notify Senders Of Viruses = no
Notify Senders Of Blocked Filenames Or Filetypes = yes
Notify Senders Of Blocked Size Attachments = no
Notify Senders Of Other Blocked Content = yes
Never Notify Senders Of Precedence = list bulk
