How can I implement proper mail attachment virus scanning ? For incoming mail, I have an antivirus security profile in place that should block virusses (smtp decoder), nothing fancy really: I notice that the PA doesn't filter attached virusses too well. Luckily (as is best practice) I have several layers of antivirus protection for mail: external spam filter --- firewall --- (spamfilter in DMZ; spam only) --- antivirus on internal mailserver --- endpoint antivirus + Outlook attachment filter So virus infected mails usually don't reach the user. However, I think it's better that they are identified and blocked at an early stage, which is not the case now. The firewall plays an important role here, I feel. I feel like PA antivirus doesn't do smtp antivirus very well. E.g. none of the test virus/spam mails from Free Email Security Check were blocked by the PA. What can I do to improve on this ? Or is PA just not up to the task ?
