Fw: My Clamd or MailScanner is sending Backscatter

[Steve' Mailing List]

When my server receives a virus, it is sending backscatter to notify the sender.  As expected most of the virus are probably spam.  I know that I am missing a setting, but I have looked through MailScanner.conf and have set the settings that I think are related (see below).  Please tell me what I am missing.

MailScanner     4.77.9
Clamd            0.95.1

OS = Whitebox EL3 (RHEL3 equivalent)

Select MailScanner settings:
Virus Scanning = %rules-dir%/virus.scanning.rules
Virus Scanners = clamd
Silent Viruses = All-Viruses
Still Deliver Silent Viruses = no


Obviously, I am missing something.  Please help me get on the right track,
Steve
