We’ve started to increase our AVS (anti-virus and anti-spam system) scanners recently.
This is our latest scanner node, a HP BL465c quad quadcore Blade with 32GB of ram. While this might seem rather excessive for a bit of email scanning, the technology behind our scanners is very CPU and memory intensive. Our scanners scan each email in seconds, matched tens of thousands of rules against the textual content of the email. We also use various optical character recognition methods to decipher image attachments.
