Last month I had implemented Pix 501 firewall for our small size company. Since last 2-weeks we are gettinglots of these viruses through the mail. I don't know much about this product means cisco Pix. What command should I enter to block these mails?
You will not be able to use the Pix by itself to block inbound email messages with virus attachments. You can combine a Cisco IDS sensor with the Pix to initiate dynamic blocking though. The best route though is to enable virus scanning on your inbound / outbound email gateways.
