Currently the Exchange domain im looking after is processing daily in the region of 50-60% of SPAM email. This is being dealt with by a "Borderware" email filtering appliance upstream from Exchange. Out of interest what are acceptable figures amongst guys here as to SPAM percentages as it is my opinion that 50-60% daily is simply too much. Our resident Security officer believes otherwise. Note we have around 6000 mailbox enabled users. Im only looking for rough figures in the ball park or opinions on this matter as opposed to a solution. As it is my belief on delving a bit deeper that this SPAM problem is the reason for the Conficker outbreak on the LAN as i can see a number of emails with malicious payloads along with malformed headers that im sure are the reason for the virus along with a poor patch management policy thats quite reactive.. hey ho...
