Sender not notified ...

[Rabellino Sergio]

Dear list (and mostly Julian ...)
  I've seen a strange behaviour in my logs:
 an email containing the virus W32/HiGuy is catched successfully by mcafee/mailscanner, but no notification are sent to the sender... From
the sendmail log I can see that the "from" address is "<>", so mailscanner could not send the virus alert back to the sender (correctly I
suppose ...)
Now the question : In the body of the message there is a real from address, it's too hard use also this information, almost in the case the
from address in the smtp protocol is empty ?

... or am I wrong ?
