Hi Len,

Barracuda is using ClamAV, isn't it? In fact, ClamAV includes the signature
for W32.Elkern.C:

$ sigtool -l | grep -i elkern
W32.Elkern.C
W32.Elkern.A

Perhaps there's some configuration problem with clamsmtpd which prevents it
from detecting the virus. How does it call/communicate with ClamAV?

Regards,
