[Mimedefang] Virus Scanners

[Adam Beatham]

Hi There,

I know this is probably really more a Sophos related question, but I wanted 
to throw it out there, incase anyone has any ideas.

I've noticed that using sophos within MD, it only appears to ever catch 
Klez, and then.. it doesn't catch that all the time.  We have basically two 
levels of virus scanning..one at our main MX (the MD machine).. that 
machine forwards to a Notes machine.  The Notes machine has NAV on it, and 
that catches a myriad of other virii.. LoveLetter, Hybris.worm, etc.   Is 
there something more I should be doing in the filter, or has anyone else 
experienced something similar?  Any ideas would be warmly welcomed!

thanks!
